The A31 'Roadworks' sign is a warning sign used in Belgium to alert drivers to upcoming road construction or maintenance. Its primary purpose is to encourage drivers to anticipate potential hazards, reduce speed, and be more vigilant about road layout changes, temporary markings, or altered traffic flow.
Upon seeing the A31 sign, you should prepare to slow down safely. Look further ahead to understand the exact nature of the roadworks, check for any supplementary panels that might specify distance or direction, and increase your following distance to other vehicles. Be ready to adjust your speed and position according to the actual road conditions and any temporary traffic management in place.
Yes, you should avoid ignoring the warning until the hazard is right in front of you. Maintaining an unsafe speed that leaves no margin for error, overtaking or changing lanes without checking if the roadworks affect your manoeuvre, or treating the sign as mere decoration, especially in poor visibility or heavy traffic, are dangerous behaviours to avoid.
A common trap is assuming the warning only applies when you are directly at the roadworks. Learners might also fail to consider supplementary panels which are crucial for understanding the scope and duration of the works. Another trap is not adjusting speed early enough or checking for other road users' altered behaviour within the roadworks zone.
Absolutely. The A31 sign often appears with supplementary panels providing details like distance to the works, duration, or specific vehicle restrictions. It can also be complemented by temporary traffic lights, cones, barriers, revised lane markings, or instructions from traffic controllers. Always assess the full situation presented to you.
