The South African National Roads Agency says upgrades on highways in Gauteng will continue until 2011, and therefore motorists must learn to live with the chaos until then.

A motorist, who claimed he was running late for work on Friday, drove in a section of road blocked off for construction.

He crashed into a construction worker, breaking the man's leg, before being arrested on charges of reckless and negligent driving.

The motorist's car was also impounded and he will appear in court next week.

The agency's Alex van Niekerk says while the company understands the delays caused by road works are frustrating, motorists must obey the rules of the road.
