Speed limits and speed rules
Quick overview of speed limits, signs, and rules that are often confused.
Part 12 of 50: Traffic Rules in Practice
Speed Limits in Brief
| Area or Sign | What You Need to Know | Typical Action |
|---|---|---|
| Built-up area | 50 km/h if not otherwise posted | Look for zone signs and cancellation |
| Outside built-up area | 80 km/h if not otherwise posted | Adjust according to visibility and conditions |
| Posted speed limit | Sign overrides standard limit | Follow the sign until it is cancelled |
| Warning signs and conditions | Speed must be adapted to risk | Slow down early and increase margins |
Three Rules of Thumb
- Speed is about visibility, road conditions, and traffic, not just signs.
- Zones last until they are cancelled, often with a new sign.
- Use the principles from positioning, speed, and distance when in doubt.

How to recognize this topic on the test
On the class B theory test, speed limits and speed rules is usually tested through a practical situation, not as an isolated fact. Read the whole question before looking at the answer options. Ask yourself who has responsibility, which risk is greatest, and what gives the best safety margin.
- Connect the rule to a practical driving situation: what do you see first, who is affected, and which action gives the best safety margin?
- Look for small details in the question, such as signs, speed, visibility, road conditions, positioning and whether another road user has already started an action.
- Choose the answer that shows early risk awareness. On the theory test, the right answer is often the one that prevents danger, not merely the one that is barely legal.
Common mistakes to avoid
- Memorizing a rule without connecting it to positioning, speed and cooperation.
- Overlooking words such as “before”, “after”, “at” or “may” in the question.
- Choosing an answer that is legal in theory but poor defensive driving in practice.
How to practice further
Use this article as a checklist after taking a practice test. If you answer a question about this topic incorrectly, write down what you missed: rule, sign, positioning, speed, responsibility or an exception. Then take a few new questions on the same topic before mixing it back into a full test.
