How the exam asks it

At a roundabout just outside Stadskanaal, alongside the N31, you see no sign at all and no shark's-teeth markings. A cyclist is entering the roundabout from your right; you are already driving on the roundabout. What applies?

  1. You have priority, because traffic on the roundabout always goes first
  2. You have priority, because the cyclist comes from the right and cyclists must always wait on a roundabout
  3. The cyclist has priority, because without a sign the rechts-regel applies to entering traffic
Show the answer

Correct answer: The cyclist has priority, because without a sign the rechts-regel applies to entering traffic

Without a sign/shark's-teeth the rechts-regel applies: the entering cyclist has priority

Why learners get this wrong: Traffic already on the roundabout always has priority over traffic entering — sign or no sign.

About Roundabout: who has priority?: which statements are correct? (multiple answers possible)

  1. On a roundabout cyclists must always wait for cars, even when the cyclist is already on the roundabout.
  2. Sign B6 and shark's-teeth already settle this unambiguously: the cyclist on the roundabout goes first.
  3. /p.84 - only WITH sign B6 and shark's-teeth markings does traffic on the roundabout have priority. With no sign at all, the rechts-regel applies: entering traffic then has priority.
  4. Whoever saw the roundabout coming first has priority over traffic already on the roundabout.

Correct answer: Sign B6 and shark's-teeth already settle this unambiguously: the cyclist on the roundabout goes first.; /p.84 - only WITH sign B6 and shark's-teeth markings does traffic on the roundabout have priority. With no sign at all, the rechts-regel applies: entering traffic then has priority.

Who 'sees it first' is not a rule — sign B6 settles this: the truck on the roundabout goes first

Why learners get this wrong: On a roundabout cyclists must always wait for cars, even when the cyclist is already on the roundabout.

About Roundabout: who has priority?: which statement is WRONG?

  1. On a turbo roundabout the ring lanes are separated by a raised lane divider with a solid line on each side; you may not cross it.
  2. The direction of travel is not a choice: on a roundabout you always drive rechtsom (anticlockwise, keeping the centre island on your left).
  3. On a roundabout the rechts-regel always applies: whoever comes from the right has priority.
  4. The arrow on your approach lane is mandatory.
Show the answer

Correct answer: On a roundabout the rechts-regel always applies: whoever comes from the right has priority.

With sign B6 and shark's-teeth it is the other way round: traffic ON the roundabout (which may be coming from your left) has priority, not entering traffic from the right. The rechts-regel only applies here in the rare unsigned situation (p.84)

Why learners get this wrong: On a turbo roundabout you may still change lanes on the roundabout itself, as long as you signal.

Open this question

Outside a built-up area you leave a turbo roundabout and approach the cycle crossing. There are shark's teeth on the cycle path, facing the cyclists. A cyclist is coming. This cyclist has priority over you here.

  1. False
  2. True
Show the answer

Correct answer: False

Shark's teeth mean: give way to traffic on the crossing road. If they face the cyclists, motor traffic goes first. Inside built-up areas it is often the other way round on single-lane roundabouts.

Why learners get this wrong: Cyclists have priority at every roundabout, including at the cycle crossing of a turbo roundabout.
