Do not block the junction — even with priority

What the exam asks here: Green light and priority together feel like a double 'yes': you may drive AND you don't need to wait for anyone.

The trap

Many learners think: If you have priority over the crossing traffic, you may always enter the junction, even if the far side is at a standstill.

The rule is: The blocking prohibition is independent of the priority question: you may only enter a junction if you are sure you can drive through or clear it again quickly. If the far side is at a standstill, you wait, priority or not

Challenge

Green light and priority together feel like a double 'yes': you may drive AND you don't need to wait for anyone. The CBR exam designer tests exactly that feeling. The book poses the blocking prohibition as a separate question, independent of priority: CAN you actually get through, or will you end up stuck in the middle of the junction?

The model

You may only enter a junction if you can drive straight through or clear it again quickly (Book p.103) — priority or a green light changes nothing about that. Two named exceptions: waiting for oncoming traffic when turning left on a priority road, and giving way to a priority vehicle (Book p.104).

Core

If you must stop to give way to other traffic, you keep the passage for the crossing traffic as clear as possible. That is why you may only enter a junction if you can drive straight through or clear it again quickly (Book p.103). This duty is not tied to who has priority. The book names only two exceptions where you may stop on the junction: traffic turning left on a priority road waiting for oncoming traffic to pass, and giving way to a priority vehicle (Book p.104). Neither exception says 'because you yourself have priority over the crossing traffic.' It follows that: even if you have priority over the crossing road, you still may not enter if the far side is at a standstill — the blocking duty binds a driver with priority too.

Why it matters

Someone who relies on priority or a green light and still drives into the queue blocks the junction for every crossing direction at once — including emergency services that can no longer get past. On a busy ring road like around the A13 near Montfoort, this creates a gridlocked junction within a single cycle that nobody can resolve without reversing.

Active recall

At a junction in Schoonhoven you have a green light and priority over the crossing traffic. Right after the junction traffic is completely gridlocked, no room to drive through. What do you do?

Teach back

Explain: why may you not enter a junction if the far side is at a standstill, even if you have priority yourself? And which two exceptions does the book name?

Memory hook

Only enter the junction if you can also get out again. Priority says who may go — not whether it fits.

Signs and law

Test yourself

On your way to a Xenos in Montfoort you approach a junction with a green light and priority over the crossing traffic. Right behind the junction the queue is at a standstill — no room at all. May you enter the junction?

Show the answer

You may only enter a junction if you can drive straight through or clear it again quickly (Book p.103) — priority or a green light changes nothing about that. Two named exceptions: waiting for oncoming traffic when turning left on a priority road, and giving way to a priority vehicle (Book p.104).

Exam questions on this topic

About Do not block the junction — even with priority: which statements are correct? (multiple answers possible)

  1. If you have to let a priority vehicle (blue flashing light and two-tone horn) go first, you may move onto or stand on the junction when that is needed to make room.
  2. Even a driver who wants to turn left on a priority road and waits for oncoming traffic must stay before the junction.
  3. The rule applies to everyone entering the junction, even on a green light: if the far side is at a standstill, you keep the passage clear and wait before it.
  4. If traffic beyond the junction is stuck, you may drive halfway onto the junction and wait there.

Open this question

In Montfoort you are driving on a priority road and want to go straight on. The far side of the junction is at a standstill, so you wait just before it. Behind you an ambulance with a blue flashing light and siren approaches and needs to cross the junction. What do you do?

  1. You drive on into the queue, because you have priority over the crossing traffic
  2. You stay before the junction, because standing on it is forbidden now as well
  3. If needed you move a little onto the junction, so that the ambulance can get past
Show the answer

Correct answer: If needed you move a little onto the junction, so that the ambulance can get past

False — you think the ban on standing on the junction applies now too. If you have to let a priority vehicle go first, you may move onto or stand on the junction when that is needed to make room

Why learners get this wrong: If you have priority over the crossing traffic, you may always enter the junction, even if the far side is at a standstill.
