1 . Beginning in what year were converter dollies required to be manufactured with ABS?
Converter dollies are not required to have ABS.
Dollies manufactured on or after March 1, 1998 must have Anti-Lock Braking Systems (ABS). A dolly with ABS must be identifiable by a yellow lamp on its left side.
2 . To stop in a vehicle that uses air brakes, the driver should:
Pull the brake pedal up.
To make a normal stop in a vehicle with air brakes, push the brake pedal down. The harder the pedal is pressed, the more air pressure is released.
3 . If an Anti-Lock Braking System (ABS) is equipped on a trailer but not on a tractor:
The tractor and trailer can still be used together.
A vehicle being equipped with anti-lock brakes on only the tractor or only the trailer provides additional control during braking.
4 . Bicyclists are:
Not allowed on the roadway.
Bicyclists are considered vehicle operators and, with certain exceptions, must obey the same laws as other traffic. They may ride on the shoulder or berm, but are not required to do so. They may also travel at less than the minimum posted speed limit without being cited for a traffic violation.
5 . If an Anti-Lock Braking System (ABS) malfunctions:
The brakes will not work.
On a vehicle with ABS, a yellow malfunction lamp on the instrument panel will illuminate to alert you if the braking system is not working.
6 . When coupling a triple trailer rig:
The order in which trailers are coupled is not important.
When coupling a triple trailer rig, you should first couple the trailer immediately behind the cab. Connect the second and third converter dollies and trailers in order.
7 . If the brake pads rub against the brake drums and create too much heat:
The air compressor will kick on to cool the brakes.
