Unless otherwise posted, the speed limit is ____ on streets and highways.
- 70 mph
- 55 mph ✓
- 45 mph
- 30 mph
Answer: B. 55 mph
Unless otherwise posted, the speed limit is 55 mph on streets and highways.
Why this is the answer
The handbook lists default maximum speeds in its speed limit section: 30 mph in a municipal, business, or residential area, and 55 mph for streets and highways. Both figures apply as maximums except where signs post a different limit, so the general street-and-highway figure is the 55 mph one. The handbook also says you must know and obey the limit, and that driving slower than the flow of traffic means keeping right so others can pass.
Why the other answers are wrong
- A. 70 mph — 70 mph appears in the handbook only as an example of a posted highway limit that brings a 50 mph minimum, not as the default for streets and highways.
- C. 45 mph — 45 mph is not listed as a default speed limit anywhere in these passages.
- D. 30 mph — 30 mph is the default maximum for municipal, business, or residential areas, not the general figure for streets and highways.
Remember it
Two numbers to keep apart: 30 in town and business districts, 55 out on the open street and highway unless a sign says otherwise.
