What to do if…
your windshield or windscreen has cracked while you are driving

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

If the crack affects your forward view, is spreading, or conditions will make visibility worse, do not keep driving normally. Move only as far as needed to reach the nearest safer place, or call roadside assistance, your insurer, a glass repair service, or a tow.

Do not do these things

  • Do not keep driving just to “see if it gets worse” if the crack is in your view or distracting you.
  • Do not stand beside traffic to inspect the glass.
  • Do not attempt a repair while stopped on a shoulder or close to moving traffic.
  • Do not blast very hot defrost onto a cold windshield, because rapid temperature changes can make damage spread.
  • Do not put tape, film, paper, or objects anywhere that reduces your view or creates glare.
  • Do not rely on a quick guess about legality; state rules vary, and the immediate issue is whether you can see clearly and control the vehicle safely.

What to do now

  1. Put safety before the glass. Keep your hazard lights on, stay aware of traffic, and inspect the windshield only from a position that does not put you in danger.
  2. Check the view from the driver’s seat. If the crack or chip is in your line of sight, makes you move your head to see clearly, creates distortion, shows whitening or branching lines, or catches glare, treat the vehicle as not safe to continue normally.
  3. Check whether the situation is likely to get worse before you can stop again. Choose roadside help or a tow if the crack is growing, spidering, running toward an edge, or distracting you now.
  4. Think about the next few miles only. Rain, freezing temperatures, bright low sun, darkness, rough roads, or heavy traffic can make a cracked windshield harder to see through and may make the glass damage spread.
  5. If your view is not clear, call for help from your roadside assistance provider, insurer, glass repair service, or a towing service. If you are stopped somewhere unsafe or there is immediate danger, call 911.
  6. If your view is clear and the crack appears stable, make any driving a short relocation only. Go to the nearest safer place off fast traffic, such as a parking lot, service plaza, repair shop, or other well-lit place where you can stop properly.
  7. While relocating, drive smoothly, slow down, increase following distance, avoid potholes and curbs, and avoid strong heat aimed at the windshield.
  8. Take one quick photo of the damage and note what hit the glass if you know. This can help when arranging repair or an insurance glass claim after you are safe.
  9. If your vehicle has cameras or sensors near the windshield, ask the repair facility whether replacement may need camera or sensor calibration for your exact year, make, and model.
  10. If you are driving a commercial motor vehicle covered by FMCSA rules, treat significant windshield damage as a stop-and-report issue and contact your carrier, dispatcher, or safety contact for instructions.

What can wait

  • You do not need to decide on the roadside whether the windshield can be repaired or must be replaced.
  • You do not need to research every state rule before moving to safety.
  • You do not need to compare repair prices while you are stressed or stopped near traffic.
  • You do not need to start an insurance claim until you and the vehicle are in a safe place.

Important reassurance

Pulling over to reassess was the right first move. A cracked windshield can feel alarming because it changes what you can trust about your view, and choosing a tow or short safe relocation is a reasonable response.

Scope note

These are first steps for the immediate decision after noticing windshield damage. Later decisions about repair, replacement, insurance, commercial-vehicle compliance, or disputes may need help from a qualified repair facility, insurer, carrier, or other specialist.
