In addition, Asian regulations are typically stricter, and the relatively shorter journey distances allow trucks to forgo sleepers to save even more length.

[citation needed] Cabover trucks are widely used in the United States for refuse collection, terminal tractors, and other vocational applications requiring a tight turning radius or frequent ingress/egress by the driver.

Cabovers are also very popular in the US's light- and medium-duty truck segment where compact size is required for urban mobility without sacrificing payload; Hino (a Toyota subsidiary), Isuzu, and Mitsubishi Fuso models are a regular sight for this reason.

American company Paccar (which owns the Kenworth and Peterbilt brands) still manufactures traditional cab over engine designs for the Australian and South African markets where length restrictions still make them advantageous.

Cab over engine types dominate urban and light duty use, with conventional trucks predominating in remote and off-road areas.

The first truck in the United States was built by Autocar in 1899 using a format then called "engine-under-the-seat" and was available with optional 5 or 8 horsepower (3.7 or 6.0 kilowatts) motors.

They reintroduced the cab-over layout in 1933 with their "Camel Back" model, which allowed the cab to be tilted to access the engine.

The company produced a wide variety of truck and commercial bodies for several vehicle manufacturers such as Chevrolet, Ford, Dodge Bros., and International Harvester until 1948 when they were purchased by the latter.

Despite the COE designs' being smaller in general, over-the-road tractors can still be fully equipped with single or bunk beds.

Also, lack of a hood gives better visibility to the driver and a tighter turning radius, and significantly reduces the forward blind spots.

One critique is that the shorter wheelbase in the COE semi-trucks gives a rougher ride than those with conventional cabs, as the driver's seat is above the front axle.

This was an important consideration back then: Interior noise in the cab was between 80 and 90 dB(A), creating an unhealthy work environment.
