(Note: This is based on experiences myself or my friends have had.)
- When approaching a "blind" four-way intersection (i.e. one where you can't see whether any cars are coming or not), do not, under any circumstances, stop, regardless of any signs to the contrary. Simply flash your lights and honk your horn to "claim" the right to go through the intersection. Under no circumstances should you slow down, and it is preferred to speed up. Similarly, if approaching an intersection and you hear someone honking; honk back and indulge in a game of blind chicken.
- Numbers in circles by the side of the road are minimum speeds.
- Policemen will pull you over for no apparent reason. They like to read your ID upside down.
- If driving in Saudi Arabia, then always dress like a Saudi. In an accident with a Saudi national, the non-Saudi is always at fault; since the non-Saudi does not understand the driving rules documented here.
- Lane markings are there for decorative purposes. Two broken lines spaced a few metres apart mean "drive five cars across here here". If another driver drives past you at 150 km/h so close that he takes out your left rear view mirror, then that's his way of telling you that there was too much space empty on your right hand side.
- Traffic lights are not always automatically controlled. Look for a police officer sitting in a box that's on stilts. He controls the traffic light. If you really need to go, then hurl insults/offer bribes at said officer to get him to change the lights in your favour.
- Only wimps turn left from the left lane. If you are a bus driver, feel free to swerve your bus through five lanes of traffic to get to the off-ramp.
- Beware of donkeys. In particular, avoid hitting a country farmer's donkey. He is likely to want the donkey put in the back of the ambulance and taken to hospital with you; indeed, the ambulance driver is likely to agree with the farmer.
- When it rains, it's safer to drive faster.
- Do not be concerned by mass honkings. It could be any of the following:
- A wedding entourage.
- Fans for a victorious soccer team.
- Bored youngsters with nothing better to do than drive around the streets and honk.
When going to pick someone up, never actually go to their apartment, simply honk from your vehicle. However, to distinguish yourself from other sounds, develop your own "family honk" so that people will know it's you.
