Towing the car before the police report exists
Moving an accident-damaged car to a workshop before filing feels efficient and quietly kills the insurance claim, because insurers and repairers both require the report. Photograph the scene, file through the Dubai Police app, Saaed or Rafid depending on the emirate, get the reference number, and only then book the recovery.
Opening the coolant cap on a hot engine
A pressurised cooling system holds coolant well above boiling point, and cracking the cap releases it as scalding spray. It is the most common self-inflicted roadside injury there is. Switch off, wait a genuine thirty minutes, and let the attending technician judge when the system is safe to open.
Serial jump starts on a battery that is finished
A battery past its second or third UAE summer that needed one jump will need another within days, and each deep discharge weakens it further. Paying AED 150–250 per rescue several times over costs more than replacing the battery in the bay on the first visit, and it strands you somewhere worse each time.
