Al Qudra Road is fast and long, with few places to pull off. If the battery light comes on while you are driving, the alternator has probably stopped charging and the car is running on the battery alone. Switch off the AC and anything else you can, and head for the next exit or service road instead of the hard shoulder.
If you do have to stop on the shoulder, put the hazard lights on and wait away from the traffic side of the car. Tell us your direction of travel and the last sign or exit you passed. We come for roadside jump starts and battery changes, and if the alternator is at fault we can arrange recovery to a workshop.
