Slow Down

Reducing the vehicle speed gives you more time to react rationally to the situation. For example, imagine you are driving at 60kmph, and you find a sign indicating a construction zone at a distance 300m ahead. After seeing the sign, if you still drive at the same speed, it will take only 18 sec to reach the site which is really a short time for you to adjust to the change in road environment. On the other hand, if you gradually slow down to 30kmph, it will take more than 30 sec which will give you enough time to take necessary safety manouevre.

• Whenever you see blinkers and/or road signs (warning about construction zone) slow down the vehicle gradually, as shown below.

• Look out for Posted Speed Limits, and try to maintain a consistent speed with the traffic flow. As mentioned before, in the absence of posted speed signs, it is necessary to drive at a speed less than 30kmph till activity zone and reduce the speed further to 20kmph upon entering the activity zone.
• Reduce your speed further, based on the road surface and weather conditions, as the posted speed limits do not account for unforeseen inclement weather, as shown below.

• At the approach to bridges, speed needs to be reduced in all cases during construction period irrespective of whether construction work is going on at these locations.
