What Is Illegal at a Roadblock?

Most of us drivers have been caught in a roadblock of sorts at some stage in our driving career. These are normally an inconvenience as well as being  a rather terrifying experience. But what is legal and what can officers not do in a roadblock?

Here’s what you should know:

Roadblocks: Back To Basics

There are two different kinds of roadblocks which take place on the roads of South Africa.

  1. The informal roadblock is a roadblock set up on major highways at random. These are normally set up to ensure that people have valid licences and discs.
  2. The K78 is an official roadblock that has been nationally or provincially approved by authorities. During this type of roadblock, police are allowed to conduct full vehicle searches, as well as full body searches.

Just note that any uniformed police officer may stop any vehicle at anytime of the day or night.

If you are on your own you may feel slightly unsafe. You are allowed to ask the officer to follow you to the nearest police station.


There are a variety of rules and regulations that you as the driver have to adhere to when partaking in a roadblock operation.

With this being said, you have the right to ensure that the roadblock is legitimate and that the people stopping you are law enforcement.

  • You are entitled to ask the officer in charge to verify that the roadblock as in fact been authorized by the right authorities concerned. This certificate needs to be signed by the National/Provincial Police Commissioner.
  • You are allowed to ask the officer that you are dealing with for his/her badge number and vehicle number on the side of the vehicle. You are allowed to write the badge and vehicle number down should you need to report the behaviour of the officer you are dealing with. You are encouraged to report any incidents that you may have to your nearest police station.


If an officer wants to arrest you because you have unpaid fines, you are allowed to refuse the arrest. An officer is only allowed to arrest you if they have been issued with a warrant for your arrest. This needs to be in writing and they need to present you with a valid copy of this warrant.

They are allowed to serve you with a summons to appear in court. This is only valid if the date is 14 days after they have pulled you over and issued you with the paper.


It is in your best interest to be civil and respectful of the officer that pulls you over during an inspection. If you refuse to do something that is asked of you and it escalates, you could be arrested for verbally abusing an officer.

  • If you are pulled over for drinking and driving and refuse to be breathalyzed. The officer will arrest you and take you to the nearest hospital for a blood test. They are legally allowed to do this.
  • If your blood/alcohol level is over the legal limit of 0.05g/per 100ml then you are technically allowed to be arrested for drinking and driving;
  • If your car is not roadworthy, the officer will most likely make you drive the car to the nearest police station and they might give you a fine;
  • According to the National Road Traffic Act, any traffic officer is allowed to ask for your license. You are required to provide these officers with your drivers license. If you refuse, you might find yourself with a fine.

Please take all these elements into account when you are next stopped at a roadblock. Remember, we have rights and responsibilities during these situations.
