Sample speed limits & control questions
Unless a different limit is posted, what is the maximum speed on a Louisiana interstate?
- A 75 mph
- B 70 mph
- C 65 mph
- D 60 mph
Show answer
B. 70 mph
Louisiana's maximum interstate speed is 70 mph unless another limit is posted. Enter the interstate at or near the speed of traffic, and do not drive below any posted minimum unless conditions require it.
On which Louisiana interstate does the handbook say parts carry a 75 mph speed limit?
- A I-12
- B I-10
- C I-49
- D I-20
Show answer
C. I-49
Louisiana's general maximum is 70 mph, but the handbook notes that portions of I-49 have a 75 mph limit. Always follow the posted sign, since it is the limit that applies to that stretch.
The speed limit is 55 mph, but heavy rain is making the road slick. Under the General Speed Law, how fast should you drive?
- A As fast as the traffic around you
- B 10 mph over the minimum speed
- C 55 mph, since that is the posted limit
- D No faster than is reasonable for the conditions
Show answer
D. No faster than is reasonable for the conditions
The General Speed Law says you must not drive faster than is reasonable for the area, road, traffic, light and weather. Speed limits assume ideal conditions, so slow down when the road is wet, icy or hard to see.
An interstate has a posted minimum speed. When may you drive slower than it?
- A Whenever you are looking for an exit
- B Never, under any circumstances
- C When weather or road conditions require it
- D Whenever you are driving in the far right-hand lane
Show answer
C. When weather or road conditions require it
You must not drive slower than the posted minimum, but on the interstate you may go slower when weather or road conditions demand it. Driving too slowly in good conditions makes other drivers take risks to get around you.
