Merging onto the highway is a special maneuver where you, as the merging driver, must always yield to traffic on the main roadway. Learn step by step how to merge safely, what to pay attention to, and which rules apply according to the CBR car theory exam.

Merging onto the highway: safely and correctly entering the roadway

Merging onto the highway is an exciting moment for many novice drivers. It is a special maneuver where you, as the merging driver, must always consider the traffic on the main roadway. In this article, you'll learn exactly how to merge safely and according to the rules, with handy tips that you can apply directly while practicing for your CBR car theory exam.

What is merging and why is it special?

Merging means that you drive onto the highway from a merging lane and join the ongoing traffic. This is a special maneuver because you, as the merging driver, are required to yield to the traffic already on the main roadway. Drivers on the highway are not obligated to make space for you, but often do so out of kindness. However, never rely on this: the responsibility always lies with you as the merging driver.

Step-by-step plan: how to merge safely

  1. Look far ahead: Keep an eye on the traffic on the main roadway and anticipate the speed and position of other vehicles.
  2. Use your mirrors: Check both your rearview mirror and your left side mirror to see if there is space to merge.
  3. Check your blind spot: Look over your left shoulder to ensure there is no vehicle next to you.
  4. Adjust your speed: Use the full length of the merging lane to match your speed with the traffic on the highway.
  5. Signal your intentions: Signaling is mandatory as soon as you actually change lanes.
  6. Merge smoothly: Choose an appropriate moment and merge without excessive speed or insufficient distance.

Weaving sections: extra caution when merging and exiting

In some places on the highway, you will encounter a so-called weaving section. This is a stretch of road where merging and exiting traffic cross each other. Specific rules apply here: drivers changing lanes must yield to traffic that remains on the same lane. So pay extra attention when changing lanes and consider other road users.

Common mistakes when merging

  • Driving too slowly on the merging lane, making it difficult to merge.
  • Signaling too early or too late.
  • Not checking mirrors properly or forgetting to check the blind spot.
  • Expecting that traffic on the highway will always make space.
  • Using the emergency lane as an extension of the merging lane (this is prohibited).

Merging and the CBR car theory exam

Merging is an important part of the CBR car theory exam. You will regularly encounter questions about special maneuvers, yielding situations, and the correct use of mirrors and turn signals. Therefore, practice not only the theory but also with practical examples and realistic situations. On Theorio, you can practice with over 150 free questions and 20+ realistic CBR simulations, so you know exactly what to expect. You learn in a fun way, receive immediate feedback, and see your chances of passing increase in real-time.
