North Dakota CDL — General Knowledge: Penalties & Licensing Practice Test

Question 1

Within three years, a North Dakota CDL holder is convicted of two serious traffic violations while driving a personal car, and one conviction leads to a license suspension. What is the minimum CMV disqualification?

Accepted Answer

60 days — Two serious violations in a noncommercial vehicle inside three years, where either conviction brings a revocation, cancellation, or suspension of the operator's license, mean at least 60 days of disqualification. Three or more mean at least 120 days.

Answer

30 days

Answer

120 days

Answer

One year

Question 2

On North Dakota's list of CDL-specific restrictions, which two codes concern airbrakes?

Accepted Answer

L and Z — Code L bars the driver from any airbrake-equipped CMV, while code Z bars only CMVs with a full airbrake system. E covers manual transmissions, O tractor-trailers, K intrastate driving, V a medical variance, and M and N passenger buses.

Answer

E and O

Answer

K and V

Answer

M and N

Question 3

You take your North Dakota road test in a commercial vehicle with an automatic transmission. Which restriction code goes on the license?

Accepted Answer

E, no manual transmission equipped CMV — Testing in an automatic limits you to automatic-transmission commercial vehicles, and the restriction list shows that limit as code E.

Answer

L, no airbrake equipped CMV

Answer

O, no tractor-trailer CMV

Answer

K, CDL for intrastate only

Question 4

How does the manual treat false information on a commercial permit or license application compared with a conviction for fraud in the same process?

Accepted Answer

False information costs the CDL for at least 60 days; a fraud conviction costs it for at least one year — Giving false information connected with getting a commercial permit or license issued means losing the CDL for at least 60 days. A fraud conviction in that process raises the loss to at least a year.

Answer

Both cost the CDL for at least 60 days

Answer

False information brings a warning; fraud brings a 60-day loss

Answer

Both cost the CDL for life

Question 5

Which endorsements does North Dakota not allow on a Commercial Learner's Permit?

Answer

P and S

Answer

N and P

Answer

S and N

Question 6

A North Dakota Commercial Learner's Permit carries the N endorsement. What limit applies?

Accepted Answer

Only empty tanks may be hauled — The tank endorsement is allowed on a permit, but the permit holder is held to empty tanks, which the restriction list shows as code X.

Answer

Tanks may be no more than half full

Answer

Only tanks under 1,000 gallons may be hauled

Answer

Only water or another non-hazardous liquid may be hauled

Question 7

According to the summary in North Dakota's N endorsement description, when does hauling several tanks on one vehicle call for the endorsement?

Accepted Answer

When each tank is rated above 119 gallons and their combined volume is 1,000 gallons or more — The summary gives two cases: several tanks that are each over 119 gallons and add up to at least 1,000 gallons, or a single tank of 1,000 gallons or more. The tanks may be attached permanently or temporarily.

Answer

When any two tanks together hold more than 119 gallons

Answer

When the tanks are permanently attached and total 500 gallons or more

Answer

Whenever more than one tank is carried, whatever the size

Question 8

Answer

One year

Answer

Three years

Answer

At least 120 days

Question 9

North Dakota restriction codes M and N both limit passenger bus driving. How do they differ?

Accepted Answer

M bars Class A passenger buses; N bars both Class A and Class B passenger buses — A driver whose road test bus is a single unit rated 26,001 pounds or more is limited to no Class A buses (M). Testing in a bus rated under 26,001 pounds brings the broader limit of no Class A or B buses (N).

Answer

M bars school buses; N bars all other passenger buses

Answer

M applies to permits only; N applies to full licenses

Answer

M bars interstate bus trips; N bars intrastate bus trips

Accepted Answer

A person at least 16 may be licensed for custom harvesting only — The legal age rule sets 18 as the floor for a Class A, B, or C license, with one carve-out: someone who is at least 16 can be issued one for custom harvesting purposes only.
