What does the B21c 'Turn Right Ahead' mandatory sign mean?

The B21c sign is a command, meaning you are legally required to turn right at the junction ahead. It's not a suggestion; it's an instruction that must be followed by the relevant road users from the point indicated by road markings or the sign itself.

How should I react when I see the B21c 'Turn Right Ahead' traffic sign?

Upon seeing the B21c sign, you must prepare to turn right. This involves checking your mirrors, signalling your intention to turn right, and executing the turn when safe to do so. You should not proceed straight or turn left if this sign is displayed and applicable to you.

Are there any exceptions to the B21c 'Turn Right Ahead' rule?

Generally, no. Mandatory signs like the B21c leave no room for interpretation regarding direction. If you cannot or do not wish to turn right, you should not proceed past the sign but look for an alternative route beforehand. The sign might specify it only applies to certain vehicle types, but if it applies to your car, you must comply.

What's a common mistake learners make with the B21c sign in the theory exam?

A common trap is confusing mandatory signs like B21c with information signs that merely suggest a route. Learners might incorrectly assume they have a choice or that the sign is just advisory. Always remember that mandatory signs require a specific action, and failing to comply is a serious offence on the road and in the exam.

What happens if the sign has a specific road user symbol on it, like for a bus?

If the B21c sign is accompanied by a symbol indicating a specific road user (e.g., a bus symbol), the instruction to turn right only applies to that category of vehicle. If you are driving a different type of vehicle (like a car) and no car symbol is present, this specific sign's instruction does not apply to you, and you can proceed normally.
