Large trucks can be ___________ times longer than passenger cars

The answer is: Large trucks can be Seven times longer than passenger cars. The passenger cars’ average length is approximately 2.5 – 3.5 meters whereas the trucks, on the other hand, had an average length of 17.5 – 20 meters (when you divide these numbers, you get around seven times longer than the passenger cars).

Introduction to trucks

Trucks or lorry are the heavy motor vehicles that are designed for transporting cargos, carrying goods, or used for special services. The trucks are majorly used for commercial purposes and can vary in size and configuration to mount special types of equipment such as suction excavators, concrete mixers, etc.

The concept of the truck emerged from that of a horse-driven wagon with some of the pioneer manufacturers having their background in the wagon business.

Thanks to a well-developed network of roads and highways in Europe and North America, trucks are a popular choice of transport for carrying the major share of the intercity freight.

Bulk materials such as ores are largely an exception with the preferred means being rail and ship while time-critical deliveries are made by air transport between cities. For all other forms of delivery, however, trucks enjoy something of a monopoly due to their ability to have the goods delivered directly to the recipients.

Large trucks can be seven times longer than passenger cars.

The first motor truck was built by the German Gottlieb Daimler back in 1896, who designed the vehicle using a belt drive and four-horsepower engine with one reverse and two forward speeds. The US-based Winton Company produced a single-cylinder six-horsepower engine delivery wagon running on gasoline power in 1898.

Motor trucks were very common during World War I, and during World War II, all horse-drawn equipment was largely replaced by these. One of the most notable vehicles of that era was the short-wheelbase jeep that came with a quarter-ton capacity and four-wheel drive technology. It was capable of carrying out a large number of military tasks.

The last quarter of the 20th Century witnessed tremendous growth in the sale of new trucks in the United States. This was largely due to the introduction of sports utility and utility vehicles which fall under the category of light trucks but are operated as family vehicles.

Light trucks account for over 90 per cent of annual truck sales in the United States as well as roughly half the number of total vehicles sold in the country at the start of the 21st Century.

This was a phenomenon unique to the market in America with the purchase of trucks worldwide taking place mainly for commercial reasons.

Frames of trucks

Frames of trucks and truck-tractors have mostly been kept separate from the body and cab except for those having very small sizes.

The frame typically comprises two channel sections of alloy steel with the standardized overall width being 86 cm or 34 inches. Tank trailers and semitrailers have now started employing the unitized or integral form of construction.

More number of modern trailer frames are designed in a way that permits standardized shipping containers to be mounted instead of the trailer bodies.

These units are designed to allow greater efficiency in the intermodal shipping of products when done through trucks, rail, and ship without the need for goods to be unloaded at the transfer points.

Length of mining trucks

If you look at the biggest trucks in the world, the F-450 will rank first followed by a pick-up truck for crew cabs and a double-trailer Mac truck. Some of the biggest trucks in the world get used for mining operations.

A mining truck is typically 6 feet tall and requires the drivers to climb up using safety handles before sitting on the seat. They are usually 50 feet in length which is same as the length of a back-hump whale.

Length of passenger cars

Any form of passenger transport that is in between 15.4 feet and 16.8 feet in length is categorized as a passenger car. A car has an average length of 15 feet or 189 inches.

The average length of a Toyota Corolla is 15 feet while a mid-sized vehicle such as a Camry or Accord ranges around 15-16 feet in length.

Vehicle size class in the United States

Vehicle size class refers to a standardized means by which cars can be classified. North American countries and English-speaking European nations use a word-based system for describing car sizes while a segment-letter system is followed in Asia.

The United States government defined size classes in Title 40 of the Federal Regulation – Protection of Environment, Section 600.315-08 Classes of comparable automobiles.

The definition of a passenger car class is done using cargo and passenger volume, or the interior volume index. A two-seater is a car that has no more than two designated positions for seating.

Light trucks that are regarded as non-passenger automobiles are classified into the following:

  • Small pickup trucks
  • Vans and minivans
  • Standard pickup trucks
  • SUVs

For models built onwards of 2013, SUVs are classified into either standard sport utility vehicles or small sport utility vehicles. SUVs and pickup trucks are classified on the basis of the gross vehicle weight rating or GVWR.

A product line that has a GVWR of more than one has its characteristic GVWR calculated on the basis of the arithmetic average of all distinct GVWR values less than or equal to 8,500 pounds for all vehicles in that specific product line.

Any automobile having a GVWR less than or equal to 8,500 pounds and other medium-duty passenger vehicles equipped with special features and determined as having a separate classification from typical automobiles will fall under the category of special purpose vehicles.

Every dimension and volume of the automobile is determined from the base vehicles of every style of the body in every car line and shall not include any optional equipment.

Passenger automobiles that either do not have a rear seat or carry a rear seat without any rear seat belts should use the area to the rear of the front seat in determining usable luggage capacity.


The US Society of Automotive Engineers (SAE) is responsible for setting a wide variety of tests for the motor vehicles. To counter the recurring noise pollution in trucks, it has developed standard noise level measurement tests.

Further, many different local, state and federal authorities in the United States have put in place a noise limit of 80 dB based on these tests run by the SAE. There are similar regulations also in place within the European Union.
