A cracked windscreen can affect visibility, and damage in the driver’s view should be taken seriously. Whether a vehicle is safe and compliant depends on the damage, its position and the applicable vehicle standards. There is no single crack-length rule that can decide every case.

What ACT guidance says

Access Canberra lists the windscreen and windows among the items checked in an ACT roadworthy inspection. The ACT Light Vehicle Inspection Manual identifies cracks or deterioration in the windscreen area in front of the driver as a reason for rejection when they interfere with the driver’s view. The current manual and inspection requirements should be checked for your vehicle and situation.

If the crack blocks your view, is spreading quickly, or the glass appears unstable, avoid driving the vehicle until you have obtained suitable advice. If you receive a defect notice, follow the instructions on it and contact the relevant ACT authority or an authorised inspection provider.

What should you do?

  • Take photos of the damage while the vehicle is parked safely.
  • Do not press on the glass or pour hot or cold water over it.
  • Ask a windscreen technician to assess whether repair or replacement is appropriate.
  • If you are unsure whether it is safe to drive, seek advice before moving the vehicle.
