Police checkpoints will be back on roads nationwide from April 1.

In October last year, the national police chief stopped checkpoints for drink-driving and other offences until transparency of the tests could be ensured.

However, checkpoints will resume from April 1.

Surveillance cameras must be operating at all checkpoints and officers must wear body cameras, to ensure transparency.

This applied to all checkpoints - whether traffic police, alcohol testing, air pollution or crime prevention.

Each checkpoint must have a sign showing the police hotline 1599 and phone number of the commanding officer in the area, in case anyone wants to file a complaint.

A police panel had looked into the pros and cons of checkpoints since their use was suspended last year, and found that without checkpoints there was a rise in the number of offences.
