Illegal drugs, prescriptions and even over-the-counter cold pills can impair driving. So can ordinary health problems, from poor vision to a stiff neck. If you're not fit to drive, let someone else take the wheel.

Know the rule

It is illegal to drive in New Jersey under the influence of any drug, or while possessing a drug without a valid prescription.

How marijuana can affect driving

  • Tracking: keeping the vehicle in its lane
  • Distance judgment: following too closely
  • Vigilance: staying attentive, not drifting or tailgating
  • Divided attention: tracking traffic, road, weather, passengers and gauges at once
Handbook p. 119 ↗

Know the rule

Any health problem, even a stiff neck, a cough or a sore leg, can affect driving. If you don't feel well, let someone else drive.

Handbook p. 120 ↗

Know the rule

State law lets the MVC retest drivers. Have your eyes tested every year or two, and every year if you're over 40. Good side (peripheral) vision and distance judgment are essential.

Know the rule

Hearing warns you of horns, sirens and screeching tires. Keep the radio turned down and never wear earphones while driving.

Handbook p. 120 ↗

Put it into practice

Your allergy medicine says "may cause drowsiness." Don't take it before driving. If you must take it, have someone else drive until you know how it affects you.
