A police officer may revoke a driver’s license for a period of thirty days:

1. Correct answer: When the driver endangers the life of a person on a pedestrian crossing
2. An arrest warrant was issued against the vehicle’s owner
3. When the driver committed an offence of holding a driver’s license that has been expired for more than ten days
4. When the passenger on the driver’s side did not wear a seatbelt

WhyA police officer can take your license for 30 days if you endangered a pedestrian on a crossing. An unbelted passenger is a different offence.
