18 Wheeler Facts
18 Wheeler Fact 1: How much does an 18 Wheeler Weigh?
According to federal regulations, the legal weight for an 18 wheeler is 80,000 pounds. Oversized trucks can weigh more but they need a special permit. Most cars weigh roughly 4,000 to 5,000 pounds.
18 Wheeler Fact 2: How long is an 18 Wheeler?
In general, the average length of an 18 wheeler is somewhere between 70 and 80 feet long. The kind of cab a driver drivers effects the length since some cabs are longer than others.
18 Wheeler Fact 3: How long does it take to Stop an 18 Wheeler?
At 55 mph, it takes a large truck two football fields to come to a stop. In general, it takes an 18 wheeler 40% longer to stop than an average car. In adverse road conditions, it can take much longer. The weight of a truck can also impact braking distance. Trucks have 10 brakes and must use special air brakes when required to decrease speed rapidly, resulting in a sound similar to that of a car hitting fan blades.
18 Wheeler Fact 4: How does an 18 Wheeler climb up and down Hills?
Most trucks today have 10 forward gears and 2 reverse gears. However, some trucks may have anywhere from 13 to 18 gears. Additionally, truck drivers use a double-clutch form of shifting that allows them to match the engine’s rpms with the appropriate gear for that rpm range. When going up or down an incline, a truck driver must select the appropriate gear given the engine’s rpms. This may result in a “slow” climb and downshifting when leveling out after a hill.
18 Wheeler Fact 5: Isn’t a truck much safer when it isn’t pulling a trailer?
When a truck driver isn’t pulling a trailer he is said to be “bobtailing.” This refers to driving only the portion of a truck known as the cab. Ironically, bobtailing can be very dangerous, especially in inclement weather, since the stabilizing weight of the trailer is absent.
18 Wheeler Fact 6: What Happens if a truck blows a tire?
Trucks have two sets of tires, referred to as a “tandem.” Ideally, if one tire blows, the other tire will continue to hold the weight of the truck until it can be repaired.
18 Wheeler Fact 7: How does a Jack Knife accident happen?
If the trailer of a truck exceeds a 45 degree angle from the cab, a jack knife accident is likely to occur. If a driver has to suddenly stop on a rainy or icy road, the truck may begin to skid and slide. If the trailer begins to come around towards the trailer at a speed faster than the cab itself, a jack knife will happen.
