Category : Priority signs

B23 - Permission for cyclists to cross traffic light signal (straight ahead or turn left, according to arrow). At red light, cyclists may proceed in the direction indicated by the panel arrow (straight ahead, or left), provided they yield to pedestrians and vehicles having priority.
What to know about this type of sign
Priority is one of the most watched driving topics online and one of the main reasons candidates fail the Belgian theory exam. The basic rule is priority to the right, but it gives way to a strict order: police officer, traffic lights, signs, then special rules for trams, emergency vehicles and manoeuvres.
- A strict order Authorised officer, then lights, then signs, then priority to the right: always in that order.
- Whoever manoeuvres gives way Leaving a car park, making a U-turn or reversing: you lose all priority.
- Frequent special cases Trams, emergency vehicles, zip merging: the exam loves them.
