Nebraska CDL Permit Test - Double

All trailers and converter dollies manufactured on or after March 1, 1998 must have Anti-Lock Braking Systems (ABS).

Strategies to avoid becoming an aggressive driver include having realistic expectations about your travel time and the possibility of delays; driving an appropriate speed and keeping a reasonable following distance; avoiding gesturing at other drivers; and keeping your hands on the wheel.

It is particularly important that you downshift before starting down a hill or entering a curve.

When approaching your vehicle to conduct an inspection, you should look underneath it to make sure there are no fresh oil, coolant, grease, or fuel leaks on the ground. Leaks can indicate unsafe defects on a vehicle.

Potential problems to check for when inspecting brakes include cracked drums; shoes or pads with oil, grease, or brake fluid on them; and shoes that are missing, broken, or worn dangerously thin.

When coupling a double or triple combination, the rearmost trailer should be the final trailer attached.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts). Strategies to help you avoid distracted driving include pre-programming radio stations; planning out your route in advance; avoiding complex or emotionally taxing conversation while driving; adjusting your mirrors before setting out; and not eating, drinking, or smoking while behind the wheel.
