While it is raining or following a downpour, parts of the road surface get flooded, which becomes an obstacle for driving. Driving on an inundated road calls for low speed and a slow drive, in order to prevent water from splashing into the engine and stop its functioning. You should keep a safe distance from the vehicle ahead. Slow down when another vehicle, particularly a large one, is coming on the opposite lane, in order to prevent waves of water from hitting the engine and causing it to stop. You should also avoid braking while driving on a flooded road and keep an eye on the vehicles behind. Brakes have reduced efficiency on flooded roads.
After driving past a flooded area, you should start braking lightly to remove moisture from the brake pads. You must take extra care and avoid driving at high speed while in a flooded area. You may lose control of the vehicle and the water may splash onto the windscreen and block your view of the road ahead. Driving at high speed near the pavement may cause floodwater to splash onto pedestrians, which is regarded as a bad manners.
Driving on parts of a road with uneven surface, you should take extra care and reduce the speed. Driving past such an area at high speed can cause you to lose control of the vehicle.

Driving on an expressway and a motorway
You can drive at a higher speed on an expressway or a motorway when compared to a normal road. The speed limit for a normal road is 90 kilometres/hour, compared to up to 120 for a motorway. On an expressway, there are no obstacles, no vehicles from the opposite direction, and no intersections. They are long roadways, so driving at a high speed is acceptable in normal traffic conditions. However, careless driving on an expressway could cause a serious accident and greater damage than on a normal road.

Before every road trip, you should study the route by calling to check the traffic condition or listening to the traffic radio. By doing so, you can avoid traffic congestion caused by road accidents. Some accidents can cause serious traffic jams. While driving on an expressway, you should pay attention to messages on the electronic notice boards that offer traffic information. Making a wrong decision may cause you to get trapped in a serious congestion on the expressway.
