Under Article 11 of the Qatar Traffic Law, you must renew your vehicle registration license within 30 days of its original expiry date. Driving your car on public roads with an expired, unrenewed license is a violation that can result in penalties, so it is important not to let the grace period lapse.
Vehicle licenses are typically valid for one calendar year from the date of issue (Article 9), so you should mark your renewal date well in advance. Some establishments may qualify for a two-year license period under Article 9's exceptions, but most individual expat-owned vehicles fall under the standard one-year rule.
To avoid fines, set a reminder a few weeks before expiry and visit the Traffic Department or use Qatar's Metrash2 app to complete the renewal. You will need to ensure the vehicle passes any required inspection, as the Licensing Authority can refuse renewal if the car is not in good mechanical condition (Article 20).
