You must not drive your vehicle at a speed greater than:
- The maximum speed limit.
- A speed that is faster than is reasonable and prudent.
- A speed that is safe for existing conditions.
- All of the above. ✓
Answer: D. All of the above.
You must not drive faster than the maximum speed limit, faster than is reasonable and prudent, or faster than is safe for existing conditions; all of the above apply.
Why this is the answer
The handbook says posted speed limits show the fastest speed you may drive only under favorable conditions, and you still must adjust your speed to weather, roadway, and traffic. It defines the safest speed as the one that lets you keep complete control and avoid collisions. It also says speeding is against the law and you must obey the limit. That means the posted maximum, a prudent speed, and a speed safe for conditions all apply together, so choosing all of the above is correct.
Why the other answers are wrong
- A. The maximum speed limit. — Obeying only the maximum speed limit is incomplete, because the handbook also requires you to slow down for weather, roadway, and traffic conditions and to keep a speed that is safe and prudent.
- B. A speed that is faster than is reasonable and prudent. — Staying only at a reasonable and prudent speed is incomplete, because you still must obey the posted maximum speed limit and adjust for existing conditions.
- C. A speed that is safe for existing conditions. — Choosing only a speed safe for existing conditions is incomplete, because you also may not exceed the posted maximum or drive faster than is reasonable and prudent.
