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.
Booking a city tow truck for a desert or beach recovery
A flatbed cannot drive on sand, so the booking fails at the point where tarmac ends and you pay for a wasted callout. Stuck in dunes or on wet beach sand, book desert recovery explicitly, send a pin, describe how deep the car sits, and stop spinning the wheels while you wait.
