History


Steam wagons

Trucks and cars have a common ancestor: the steam-powered ''fardier'' Nicolas-Joseph Cugnot built in 1769. However, steam wagons were not common until the mid-19th century. The roads of the time, built for horse and carriages, limited these vehicles to very short hauls, usually from a factory to the nearest railway station. The first semi-trailer appeared in 1881, towed by a steam tractor manufactured by De Dion-Bouton. Steam-powered wagons were sold in France and the United States until the eve of
World War I World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fightin ...

Internal combustion

In 1895

Diesel engines

Although it had been invented in 1897, the
diesel engine The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-call ...
did not appear in production trucks until Benz introduced it in 1923. The diesel engine was not common in trucks in Europe until the 1930s. In the United States, Autocar introduced diesel engines for heavy applications in the mid-1930s. Demand was high enough that Autocar launched the "DC" model (diesel conventional) in 1939. However, it took much longer for diesel engines to be broadly accepted in the US: gasoline engines were still in use on heavy trucks in the 1970s.


Electric Motors

Electrically powered trucks predate internal combustion ones and have been continuously available since the mid-19th-century. In the 1920s Autocar Trucks was the first of the major truck manufacturers to offer a range of electric trucks for sale. Electric trucks were successful for urban delivery roles and as specialized work vehicles like

. The first known usage of "truck" was in 1611 when it referred to the small strong wheels on ships' cannon carriages, and comes from "Trokhos" (Greek) = "wheel". In its extended usage, it came to refer to carts for carrying heavy loads, a meaning known since 1771. Its expanded application to "motor-powered load carrier" has been in usage since 1930, shortened from "motor truck", which dates back to 1901. "Lorry" has a more uncertain origin, but probably has its roots in the

It might derive from the verb ''lurry'' (to carry or drag along, or to lug) which was in use as early as 1664, but that association is not definitive. The expanded meaning of ''lorry'', "self-propelled vehicle for carrying goods", has been in usage since 1911.


International variance

In the United States, Canada, and the Philippines, "truck" is usually reserved for commercial vehicles larger than regular passenger cars, but includes large SUVs, pickups, and other vehicles with an open load bed. In Australia, New Zealand and South Africa, the word "truck" is mostly reserved for larger vehicles. In Australia and New Zealand, a pickup truck is frequently called a ''ute'' (short for "utility" vehicle), while in South Africa it is called a ''bakkie'' (

Heavy

Heavy trucks are the largest on-road trucks, Class 8. These include vocational applications such as heavy dump trucks, concrete pump trucks, and refuse hauling, as well as ubiquitous long-haul 4x2 and 6×4 tractor units. Road damage and wear increase very rapidly with the axle weight. The number of steering axles and the suspension type also influence the amount of the road wear. In many countries with good roads a six-axle truck may have a maximum weight of or more.


Off-road

Off-road trucks include standard, extra heavy-duty highway-legal trucks, typically outfitted with off-road features such as a front driving axle and special tires for applications such as logging and construction, and purpose-built off-road vehicles unconstrained by weight limits, such as the

. This design is almost ubiquitous in Europe, where overall truck lengths are strictly regulated, and is widely used in the rest of the world. They were common in North American heavy-duty trucks but lost prominence when permitted length was extended in the early 1980s. Nevertheless, this design is still popular in North America among medium- and light-duty trucks. To reach the engine, the whole cab tilts forward, earning this design the name of "tilt-cab". This type of cab is especially suited to the delivery conditions in Europe where many roads require the short turning radius afforded by the shorter wheelbase of the cab over engine layout. * "Conventional" cabs seated the driver behind the engine, as in most passenger cars or pickup trucks. Many new cabs are very streamlined, with a sloped hood (bonnet) and other features to lower drag.

Drivetrain

Small trucks use the same type of transmissions as almost all cars, having either an automatic transmission or a manual transmission with

for each shift, (which can lead to repetitive motion injuries), or a technique known colloquially as "floating", a method of changing gears which doesn't use the clutch, except for starts and stops, due to the physical effort of double-clutching, especially with non-power-assisted clutches, faster shifts, and less clutch wear. Double-clutching allows the driver to control the engine and transmission revolutions to synchronize so that a smooth shift can be made; for example, when upshifting, the accelerator pedal is released and the clutch pedal is depressed while the gear lever is moved into neutral, the clutch pedal is then released and quickly pushed down again while the gear lever is moved to the next higher gear. Finally, the clutch pedal is released and the accelerator pedal pushed down to obtain the required engine speed. Although this is a relatively fast movement, perhaps a second or so while the transmission is in neutral, it allows the engine speed to drop and synchronize engine and transmission revolutions relative to the road speed. Downshifting is performed in a similar fashion, except the engine speed is now required to increase (while the transmission is in neutral) just the right amount in order to achieve the synchronization for a smooth, non-collision gear change. "Skip changing" is also widely used; in principle, the operation is the same as double-clutching, but it requires neutral be held slightly longer than a single-gear change. Common North American setups include 9, 10, 13, 15, and 18 speeds.

Almost all heavy truck transmissions are of the "range and split" (double H shift pattern) type, where range change and so‑called half gears or splits are air operated and always preselected before the main gear selection.

Any towed trailer must not weigh more than GVM. * MR: Medium rigid: a rigid vehicle with 2 axles and a GVM of more than . Any towed trailer must not weigh more than GVM. Also includes vehicles in class ''LR''. * HR: Heavy Rigid: a rigid vehicle with three or more axles and a GVM of more than . Any towed trailer must not weigh more than GVM. Also includes articulated buses and vehicles in class ''MR''. ;Heavy vehicle transmission There is also a heavy vehicle transmission condition for a license class ''HC'', ''HR'', or ''MC'' test passed in a vehicle fitted with an automatic or synchromesh transmission; a driver's license will be restricted to vehicles of that class fitted with a synchromesh or automatic transmission. To have the condition removed, a person needs to pass a practical driving test in a vehicle with non-synchromesh transmission (constant mesh or crash box).

). As an overview, to drive a vehicle weighing more than for commercial purposes requires a specialist license (the type varies depending on the use of the vehicle and number of seats). For licenses first acquired after 1997, that weight was reduced to , not including trailers. Since 2013, the C1 license category allows driving vehicles over 3.5 and up to 7.5 tonnes. The C license category allows driving vehicles over 3.5 tonnes with a trailer up to 750 kg, and the CE category allows driving category C vehicles with a trailer over 750 kg.


South Africa

To drive any vehicle with a GVM exceeding , a code C1 drivers license is required. Furthermore, if the vehicle exceeds a code C license becomes necessary. To drive any vehicle in South Africa towing a trailer with a GVM more than , further restrictions apply and the driver must possess a license suitable for the GVM of the total combination as well as an articulated endorsement. This is indicated with the letter "E" prefixing the license code. In addition, any vehicle designed to carry goods or passengers may only be driven by a driver possessing a Public Driver's Permit, (or PrDP) of the applicable type. This is an additional license that is added to the DL card of the operator and subject to annual renewal unlike the five-year renewal period of a normal license. The requirements for obtaining the different classes are below. * "G": Required for the transport of general goods, requires a criminal record check and a fee on issuing and renewal. * "P": Required for the transport of paying passengers, requires a more stringent criminal record check, additionally the driver must be over the age of 21 at time of issue. A G class PrDP will be issued at the same time. * "D": Required for the transport of dangerous materials, requires all of the same checks as class P., and in addition the driver must be over 25 at time of issue.


United States

In the United States, a commercial driver's license is required to drive any type of commercial vehicle weighing or more. The federal government regulates how many hours a driver may be on the clock, how much rest and sleep time is required (e.g., 11 hours driving/14 hours on-duty followed by 10 hours off, with a maximum of 70 hours/8 days or 60 hours/7 days, 34 hours restart ) Violations are often subject to significant penalties. Instruments to track each driver's hours must sometimes be fitted. In 2006, the US trucking industry employed 1.8 million drivers of heavy trucks. There is a shortage of willing trained long-distance truck drivers. Part of the reason for this is the economic fallout from

Air pollution also threatens professional truck drivers. Over a quarter of global transport emissions are from road freight, in 2021 over 1700 million tonnes from medium and heavy trucks, so many countries are further restricting truck emissions to help limit climate change.

Good enclosure integrity is also needed to achieve positive pressure to prevent wind-driven aerosol penetration into the enclosure'','' as well as to minimize air leakage around the filtration system. Test methods and mathematical modeling of environmental enclosures are also beneficial for quantifying and optimizing filtration system designs, as well as maintaining optimum protection factor performance for enclosure occupants.


Operations issues


Taxes

Commercial trucks in the US pay higher road use taxes on a state level than other road vehicles and are subject to extensive regulation. A few reasons commercial trucks pay higher road use taxes: they are bigger and heavier than most other vehicles, and cause more wear and tear per hour on roadways; and trucks and their drivers are on the road for more hours per day. Rules on use taxes differ among jurisdictions.


Damage to pavement

The life of a pavement is measured by the number of passes of a vehicle axle. It may be evaluated using the Load Equivalency Factor, which states that the damage by the pass of a vehicle axle is proportional to the 4th power of the weight, so a ten-ton axle consumes 10,000 times the life of the pavement as a one-ton axle. For that reason, loaded trucks cost the same as thousands of cars in pavement costs, and are subject to higher taxes and highway tolls.


Commercial insurance

Primary liability insurance coverage protects the truck from damage or injuries to other people as a result of a truck accident. This truck insurance coverage is mandated by U.S. state and federal agencies, and proof of coverage is required to be sent to them. Interstate trucks in the U.S. are required to have a minimum of $75,000 in liability insurance. This includes motor carriers operating vehicles with a gross weight rating in excess of (which transport non-hazardous materials). All motor carriers operating vehicles transporting materials classified as hazardous, and which have a gross weight rating in excess of must have a minimum of $1,000,000 in liability insurance. All motor carriers operating vehicles such as hopper-type cargo vehicles or tankers with a capacity in excess of must have a minimum of $5,000,000 in liability insurance. Pricing is dependent on region, driving records, and history of the trucking operation. Motor truck cargo insurance protects the transporter for his responsibility in the event of damaged or lost freight. The policy is purchased with a maximum load limit per vehicle. Cargo insurance coverage limits can range from $10,000 to $100,000 or more. Pricing for this insurance is mainly dependent on the type of cargo being hauled.


Safety


Trucking accidents

In 2002 and 2004, there were over 5,000 fatalities related to trucking accidents in the United States. The trucking industry has since made significant efforts in increasing safety regulations. In 2008, the industry had successfully lowered the fatality rate to just over 4,000 deaths, but trucking accidents are still an issue that causes thousands of deaths and injuries each year. Approximately 6,000 trucking accident fatalities occur annually in the United States. Fatalities are not the only issue caused by trucking accidents. Here are some of the environmental issues that arise with trucking accidents: * 14.4% of trucking accidents cause cargo to spill * 6.5% cause open flames Following increased pressure from ''The Times'' "Cities Fit For Cycling" campaign and from other media in Spring 2012, warning signs are now displayed on the backs of many heavy goods vehicles (HGV). These signs are directed against a common type of accident that occurs when the large vehicle turns left at a junction: a cyclist trying to pass on the nearside can be crushed against the HGV's wheels, especially if the driver cannot see the cyclist. The signs, such as the winning design of th
InTANDEM road safety competition
launched in March 2012, advocate extra care when passing a large vehicle on the nearside.


HGV safety in the EU

In-vehicle speed limitation is required applying a 90 km/h limit to commercial vehicles over 3.5 tonnes. Front, side, and rear underrun protection is required on commercial vehicles over 3.5 tonnes. Trucks must be fitted with blind-spot mirrors that give drivers a wider field of vision than conventional mirrors.
