District Of Columbia CDL Permit Test - Double

Doubles and triples should be inspected using the same process that is used to inspect other vehicles. A driver should expect a properly thorough inspection of a double or triple to take more time than an inspection of a smaller vehicle.

A large vehicle may need to swing right to make a left turn. If an intersection has two left turn lanes, the driver should choose the righthand land to begin their turn.

You can build up a "debt" of sleep if you do not sleep for adequate amounts of time. You can only catch up on the time that you "owe" by getting more sleep.

Double and triple combinations are the most vulnerable to turning over as a result of the "crack-the-whip" effect.

More than half of all accident-related truck driver deaths are a result of truck rollovers. To help prevent a rollover, be sure to load cargo low to the ground and centered on your rig. Take corners slowly and carefully.

Swerving out of the way of a hazard is sometimes safer than trying to stop before reaching the hazard. You can usually turn away from something more quickly than you can come to a complete stop. However, swerving while in a vehicle that is either top-heavy or pulling multiple trailers may result in a rollover.

If you are involved in a crash, the three basic things you need to do are protect the area, notify the proper authorities, and care for anyone injured. It is important to protect the accident site immediately after the accident occurs to help prevent another crash from happening in the same location.
