Everyone has a role to play in making our roads as safe as they can be, that is especially true in construction zones. Drivers in New Brunswick are reminded that if they get caught speeding in highway construction zones they face double the minimum fine. It is important to stay diligent while driving in construction zones. Avoid changing radio stations, using a cell phone, etc. while driving in a work zone. Drive carefully and slowly through the construction site; always obey the posted speed limits in the work zone area. Pay close attention and heed directions on work zone warning signs
These road construction workers do their part to keep you out of
harm’s way from heavy equipment and road hazards. However, they are
vulnerable to passing traffic or distracted drivers. There is literally
nothing between them and the thousands of pounds of steel in your
vehicle. Please, do your part to keep them safe.
When you see road construction signs or workers wearing high visibility vests on the roadside remember to:
Slow down. Obey the signs and directions.
Stay alert. Do not use your phone, text or take pictures.
Show respect for those working on the road.
