Standing beside the car on a highway shoulder
The instinct after a breakdown is to hover near the car, inspect the damage and wait by the driver's door. On E311 or E11 that puts you a metre from traffic passing at 120 km/h. Exit on the barrier side, get behind the barrier, and stand well back from the car so that if it is struck you are not part of the collision.
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.
