You are driving at the posted speed limit, but heavy rain has made the road slippery and visibility poor. What does the manual say about your speed?
-
A.
You cannot be ticketed since you are within the posted limit.
-
B.
You may be ticketed for driving too fast for conditions. Correct
-
C.
You must reduce speed to at least 20 mph below the posted limit.
-
D.
You must turn on hazard flashers and continue at the posted limit.
The answer is "You may be ticketed for driving too fast for conditions."
The manual is explicit that staying at or under the posted limit does not shield you from a ticket when conditions are poor. Drivers pick A because they treat the posted number as a legal safe harbor, but the manual states posted limits assume ideal conditions, and a ticket for driving too fast for conditions still applies in rain.
The traps in the wrong answers
A. You cannot be ticketed since you are within the posted limit.
The manual directly contradicts this: staying at the posted number is not a defense when the road is wet, icy, or hard to see. Treats the posted sign as an absolute shield, the way a driver would defend a ticket by pointing at the speedometer.
C. You must reduce speed to at least 20 mph below the posted limit.
The 20-mph reduction is the Move Over Law rule for passing an emergency response area or disabled vehicle when you cannot change lanes, not a general wet-weather rule. Pulls the 20-mph figure from the Move Over Law and applies it to ordinary bad weather.
D. You must turn on hazard flashers and continue at the posted limit.
Hazard flashers are called for when a breakdown drops you below 40 mph on a limited-access highway, not as a substitute for slowing down in rain. Borrows the below-40-mph hazard-flasher rule and treats it as permission to keep the same speed in rain.
