Numbers to know

3 questions from the North Dakota practice test

1. 1. What is the maximum speed for a rural Interstate highway unless another speed is posted?

   1. 80 miles per hour
   2. 70 miles per hour
   3. 65 miles per hour
   4. 50 miles per hour
   Show answer

   80 miles per hour. North Dakota lists 80 miles per hour as the maximum on rural Interstate highways unless a different speed is posted. The 70 mile figure belongs to paved and divided multilane highways, while 65 applies to a rural paved two lane highway only when posted. The 55 mile figure covers gravel, dirt, loose surface roads and certain unposted county or township roads. Identify the road type before selecting the number.

2. 2. What is the maximum speed when approaching a railway crossing where the view of the track is obstructed?

   1. 45 miles per hour unless otherwise posted
   2. 25 miles per hour unless otherwise posted
   3. 20 miles per hour unless otherwise posted
   4. 55 miles per hour unless otherwise posted
   Show answer

   20 miles per hour unless otherwise posted. When the driver's view of a railway crossing is obstructed, the maximum approach speed is 20 miles per hour unless another speed is posted. The 25 mile choice belongs to a business or residential district, while the higher numbers fit open roadway categories rather than this limited view. Reduce speed early enough to see the crossing and stop if needed. The visual obstruction is the cue that activates this special limit.

3. 3. Under current North Dakota law, what minimum fee applies to speeding 1 to 10 mph over the limit in a highway construction zone while construction workers are present?

   1. $80
   2. $40
   3. $150
   4. $250
   Show answer

   $150. North Dakota sets a $150 fee for exceeding a highway construction zone speed limit by one through ten miles per hour, plus $2 for each mile per hour beyond ten over the limit. The fee applies only when construction workers are present and the posted sign states Minimum Fee $150. Older manuals list an $80 minimum, which is no longer the current amount, and $40 is the school zone base fee. Slow down whenever you see workers in the zone.
