15 . If oil and water build up in your vehicle's air tanks, the brakes:
Will be extremely sensitive.
Air tanks should be drained daily to remove water and oil buildup. An excess of oil and water in the air tanks can interfere with proper brake function.
16 . The easiest way to recognize that your trailer has begun to skid is to:
Watch the jackknife warning light on the control panel.
The easiest way to spot a trailer skid is to use your mirrors. Any time you brake hard, check your mirrors to ensure that your trailer is still in its proper position.
17 . If colors are being used to distinguish glad hands, which color is used for emergency lines?
Red
When trailer air lines are color-coded, the service lines are generally blue and the emergency lines are generally red.
18 . If unsure if a trailer is equipped with ABS, you can:
Remove a tire and look for the ABS sensor on the axle.
Trailers and converter dollies built on or after March 1, 1998 are required to have Anti-Lock Braking Systems (ABS). This will be indicated by the presence of a yellow malfunction lamp. You can determine if older trailers have ABS by checking under the trailers for ECU and wheel speed sensor wires coming from the back of the brakes.
19 . The trailer hand valve should:
Be used on slippery surfaces.
The trailer hand valve works the trailer brakes but should only be used when testing them. Using it while driving could create a skid. Never use the trailer hand valve while parking because doing so may release the air pressure from the braking system, releasing the brakes that are holding the vehicle in place.
20 . Avoid needing to make sudden lane changes by:
Pulling off the road and waiting when there is high traffic.
Making a sudden lane change can be dangerous when driving a combination vehicle. Avoid the need to make a sudden lane change by looking down the road for upcoming obstacles that will require you to change lanes.
