AR Speed Limits
What is the typical maximum posted speed limit on a rural interstate highway in Arkansas?
- 60 mph
- 70 mph
- 75 mph ✓
- 85 mph
The answer explained
Arkansas sets a top posted limit of around 75 mph on its rural interstates. Urban sections, work zones, and tunnels are typically lower. Posted limits are the maximum legal speed under ideal weather, traffic, and visibility. Arkansas requires a passing score of at least 80 percent on the written knowledge exam. The basic speed law overrides the posted number when conditions change. Driving 65 in heavy fog or freezing rain can still be cited as too fast for conditions even when the sign reads 75.
Why this rule exists
Speed is the single largest predictor of crash severity. The kinetic energy of a vehicle scales with the square of its speed, so a small reduction at highway speeds dramatically lowers the force of impact in a collision.
The most common mistake
Drivers assume the posted limit is a target rather than a maximum and pace themselves at five or ten over. In Arkansas this can be enforced as reckless driving once the speed climbs high enough above the limit.
Arkansas specific note
Arkansas requires a passing score of at least 80 percent on the written knowledge exam. For this question in particular, the Arkansas Office of Driver Services aligns with the standard interpretation explained above. Always verify against the most recent Arkansas driver handbook before relying on these details for the live exam.
Study tip
Memorize three numbers per state: the rural interstate maximum, the typical urban limit, and the school zone limit. Most exam questions test these three.
