The B2a sign means you are prohibited from turning left at the location where the sign is placed. This is a mandatory instruction, and drivers must comply with it to ensure traffic safety and order.
When you encounter the B2a sign, you must not turn left. You should continue straight on, turn right if permitted, or take another lawful route that allows your intended movement. Always look ahead for any supplementary plates that might add details to the restriction.
The general rule is that you must not turn left. However, supplementary plates below the B2a sign might specify exceptions, such as the restriction applying only to certain types of vehicles, during specific times of the day, or for a limited distance. If no such plate is present, the prohibition applies to all vehicles.
A common mistake is assuming you can turn left if other drivers are doing so, or if there's no immediate police presence. Another trap is not checking for supplementary plates, which could change the scope of the restriction. Always adhere to the sign's explicit instruction unless a plate indicates otherwise.
No, the restriction imposed by the B2a sign remains in effect until you pass an 'end of prohibition' sign, reach the end of a controlled zone, or encounter a new sign that provides different instructions. Simply passing the junction does not end the restriction if the sign continues to be displayed.
