Which of the following statements about retarders are correct? -
ANSWERSRETARDERS HELP SLOW A VEHICLE, REDUCING THE NEED FOR

RETARDER MAY CAUSE THEM TO SKID. 3) YOU SHOULD TURN THE RETARDER
OFF WHENEVER THE ROAD IS WET, ICY, OR SNOW-COVERED --- (While retarders
can help reduce the need for braking, they can make a skid more likely in inclement
weather or whenever your wheels have poor traction. Therefore, you should always turn
off your retarders in poor weather.)
If your brakes fail on a downgrade, what should you do? - ANSWERSUSE AN ESCAPE
RAMP --- (Escape ramps are designed with soft gravel, upgrades, or both, to slow down
vehicles that experience brake failure on a downgrade. If your brakes have failed on a
downgrade, use an escape ramp if its available. Before you start a trip, learn the
locations of escape ramps on your route. If no escape ramp is available, take the safest
escape route you can, such as an open field or a side road that flattens out or turns
uphill.)

openers may be exempt. Texas follows federal regulations on this.)
