Open this question

In Klundert the municipality is discussing where a new 30 km/h zone should be placed. Which two locations best fit the book rule?

  1. A street with a lot of mixed (fast/slow) traffic, and a street near a school
  2. A street where pedestrians may walk on the roadway, and a street with only parking spaces
Show the answer

Correct answer: A street with a lot of mixed (fast/slow) traffic, and a street near a school

Why learners get this wrong: In a 30 km/h zone, just like on a woonerf, a maximum speed of 15 km/h applies.

Open this question

In Steenbergen you enter a 30 km/h zone over a lowered kerb. Later you leave the zone at a junction of two equal streets, without a lowered kerb, shark's teeth or signs. A car is approaching from the left. How do you act on entering and on leaving?

  1. Entering: traffic from the right goes first; leaving: you go before the car from the left
  2. Entering: give way to everyone; leaving: you go before the car from the left
  3. Entering: give way to everyone; leaving: you let the car from the left go first
Show the answer

Correct answer: Entering: give way to everyone; leaving: you go before the car from the left

False — you treat the end of the zone as an uitrit. The end of a zone is not always an uitrit; at this ordinary equal junction traffic from the right has priority, so the car from the left must let you go first

Why learners get this wrong: When entering a 30 km/h zone via an inrit, no special priority rules apply — it is just an ordinary road.
