Impaired driving laws — North Carolina Permit Test

Impaired driving laws on the North Carolina permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

DWI laws allow enforcement agencies to set up road blocks to check for impaired drivers.

A checkpoint catches drivers who have not yet done anything visible. The law allows it because impairment hides until it does not.

Allow enforcement agencies to set up road blocks to check for impaired drivers;

North Carolina Driver Handbook, p.31

DWI laws prohibit drivers from consuming any alcoholic beverage, including beer, while driving, and prohibit carrying an open container of alcohol in the passenger area of the car.

An open can within reach is a drink waiting to happen. The law keeps it out of the part of the car where the driver sits.

Prohibit the transport of an open container of any alcoholic beverage, including in the passenger area of the car;

DWI laws require anyone convicted of DWI a second time to serve a jail sentence.

A first conviction is treated as a lesson. A second one shows the lesson did not take, and the sentence is no longer optional.

Require persons who are convicted of DWI for the second time to serve a jail sentence;

North Carolina Driver Handbook, p.31

Anyone convicted of DWI must obtain a substance abuse assessment before driving privileges are reinstated.

The license comes back only after somebody has looked at whether drinking is a problem. The assessment is that look.

Require anyone convicted of DWI to obtain a substance abuse assessment prior to the reinstatement of driving privileges.

North Carolina Driver Handbook, p.32

If you are convicted of DWI while your license is already revoked for an earlier DWI, the court may order your vehicle seized and sold.

Driving drunk on a license already lost for drunk driving leaves the court one tool: taking the car away.

If you are convicted of DWI while your license is revoked for an earlier DWI conviction, the court may order your vehicle seized and sold.

North Carolina Driver Handbook, p.32

Alcoholic beverages, open or closed, may not be possessed in the passenger area of a commercial motor vehicle on any highway, street or public vehicular area.

For a truck or bus driver the rule is stricter than for a car. Even a sealed bottle up front is a violation.

Prohibit the possession of alcoholic beverages (open or closed) in the passenger area of a commercial motor vehicle while upon any highway, street or public vehicular area;

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
