A delivery rider's 20 minutes

Traffic, heat and a busy kitchen all add minutes. A message every two minutes won't make the bike go faster, but it can pull the rider's eyes off the road.

Give a clear address and a landmark, answer your phone, or meet the rider at the door or in the lobby.

A late order is often the kitchen or the traffic, not the rider. A low rating can cost them work. A small tip on a 44°C day means a lot.

If you can, order outside the hottest hours. A cold bottle of water at the door is a small thing that riders remember.

Motorbikes are small and easy to miss in a mirror. Check your blind spot before you change lanes or turn.

Don't tailgate a rider or squeeze past them. A bike may brake hard or swerve around a pothole.

Close calls often happen when a car pulls out. Wait until you're sure the way is clear, of bikes too.

Look in the mirror and over your shoulder before you open a car door on the road side.

Every summer, from 15 June to 15 September, outdoor work in direct sun is banned from 12:30 to 3 pm. The Ministry of Human Resources and Emiratisation (MOHRE) says delivery riders can't be forced to work in those hours. If you do work then, you shouldn't be given more than three orders, and deliveries on foot aren't allowed.

MOHRE says there are more than 12,000 air-conditioned rest stations for delivery riders across the UAE, with seats and cold water. In Dubai, the RTA also opens temporary rest areas at metro and bus stations.

In Dubai, RTA and Dubai Police rules require a certified helmet, a reflective vest, gloves, long sleeves, long trousers and proper boots. Delivery bikes must stay out of the fast lanes: the two left lanes on roads with five or more lanes, and the left lane on main roads with three or four.

Drink before you feel thirsty, pull over to use your phone, and wait at the red light. Being a few minutes late can cost a rating. A crash can cost much more.
