Roadside Barrier


Slip Road off PIE to Upper Bt Timah Road

 1. There is an object to the left of the truck, where the road divides. What is this object? Why is it placed there and why is it designed the way it is?

2. Comment on the safety of the man on the back of the truck.

3. Investigate what would happen to the truck (and the man on the back) if the truck hits the divider object at 80 km/h. How would it change if the object was not there?
