DMV License Restrictions – Your Quick Guide

Ever looked at your driver’s license and seen a little code you don’t understand? Those letters and numbers aren’t just decoration – they’re real limits that the DMV puts on what you can do behind the wheel. Ignoring them can mean a fine, points on your record, or even losing your licence altogether.

This page breaks down the most common restrictions, explains why they’re there, and shows you how to get rid of them if you’re ready. No jargon, just clear steps you can take today.

Common Restrictions You’ll Encounter

DL – Driver’s License (Standard): The baseline licence for most drivers. If you see no extra letters, you’re free to drive any vehicle you’re qualified for.

A – Corrective Lenses: Requires you to wear glasses or contacts while driving. If you fail a vision test, the DMV adds this restriction.

S – Automatic Transmission: Limits you to driving automatic cars only. It’s usually given after a road test in an automatic vehicle.

M – Motorcycle: Allows a motorcycle endorsement; without it, you can’t legally ride a bike.

B – Bus/Truck: Adds a commercial driver’s license (CDL) restriction for larger vehicles. You’ll need extra training and tests.

R – Restriction for Medical Reasons: Could mean a condition like epilepsy, diabetes, or heart disease that needs monitoring. The DMV will ask for a doctor’s report.

Each restriction comes with a short code on your card. If you spot one you didn’t expect, it’s worth checking your driving record online or calling the local DMV.

How to Remove or Adjust Restrictions

First, find out why the restriction was added. Most states let you request a copy of the medical or vision report that triggered it. If you’ve corrected the issue – for example, you got new glasses or completed a CDL training program – you can apply for a lift.

Step 1: Gather proof. For vision, that’s a current eye exam. For medical conditions, a doctor’s clearance form. For CDL, a completed course certificate.

Step 2: Fill out the appropriate DMV form. Look for “Restriction Removal” or “License Update” on the DMV website. Many states let you upload documents online.

Step 3: Pay any fees. Most states charge a small processing fee, usually under $30.

Step 4: Wait for confirmation. Some states process changes within a week; others may need a brief in‑person visit.

If you’re still unsure, call the DMV’s customer service line. They can tell you exactly what paperwork is needed and whether you need to take a test.

Remember, driving with an unremoved restriction isn’t just risky – it’s illegal. Even if you feel fine, the law treats the restriction as a binding rule.

Bottom line: read the codes on your licence, understand why they’re there, and act fast if you’ve fixed the underlying issue. Keeping your record clean means fewer headaches, lower insurance rates, and the freedom to drive whatever you need.
