The Driving Standards Agency (DSA) may have to cancel driving tests due to bad weather conditions, vehicle problems or other reasons. Your test will be automatically rebooked by the DSA. You must call your test centre if there is snow or ice in your local area on the day of your test. If you are informed your test cannot go ahead, a new appointment date will usually be sent to you within 3 working days. This could take up to 7 days when the bad weather goes on for longer. Remember bad weather can sometimes lead to longer waiting times for practical test appointments.
