Dealing with Floods

Although flash floods are rare, when they occur, they can wreak havoc. Floods can occur quickly, and can be extreme dangerous. The most important factor in dealing with floods is to avoid them in the first place.
Last week saw severe s weather, along with floods in certain areas of the country for and more rain is expected.
When the weather is heavy you should listen to local radio traffic reports, monitor social media, and check online websites for advisories and cautions. If roads on your normal route are flooded, avoid them and seek alternatives, even if it means you will take a lot longer to get to your destination,
The Automobile Association advises that if you meet a flood anyway, some important rules need to be followed. Firstly, if possible, turn around and drive away from the flooded area. If this isn’t possible, try and gauge the depth of the water ahead by watching other vehicles negotiate a specific stretch of water. Do not attempt to go through this if it is deeper than 20 centimetres as the water may damage mechanical and electronic components of your vehicle.
Some other tips to negotiate flooded roads include:

• Obey authorities and emergency personnel who tell you to avoid driving on a specific road. If a road has been closed, obey the closure, and drive the alternative route,
• Do not try and cross a body of water, even if you think you can make it through, as the water may be deeper than you think, and the road may have eroded since you last used it,
• If there is a risk you will be caught in a flood, pull off the road and look for higher ground,
• If you do pull off, make sure you leave enough space for emergency vehicles to pass you,
• If you have no alternative but to drive through a body of water, drive as slow as possible in first gear with both hands on the steering wheel. This will give your car the necessary traction to move forward. Driving fast may result in aquaplaning,
• Ensure you are as visible as possible. Switch on your headlights,
• If your car is being surrounded by water, unfasten your seatbelt (and those of any children with you), unlock your doors, and open your windows. If water starts entering through the windows, get out of the vehicle and wade to the nearest point of safer higher ground. Remember, you are more important than your car,
• If your car is suddenly submerged and your windows aren’t already open, try and break a window and swim to the nearest point of safety,
• If you are caught in a flood, be patient and remain calm. The AA, and emergency services will get you but there may be delays as they have to negotiate the same hazards,
• Be especially cautious at night, or when visibility is low, as it may be harder to see floods ahead
• Never drive through fast flowing water that you know you will not be able to walk through.
• If in the bush check the depth and undersurface of the water by walking through it.
If you do make it through the water, check your car for any damage, and feather the brakes to dry them. Have an expert examine your vehicle afterwards for any possible damage.
If your car has been partially or completely submerged, and you have stopped in a body of water, don’t try and start it unless you have had a technician look at it as this may result in damage to the engine.
Finally, it is important to remain as calm as possible in these situations and assess the best way out. If this means leaving your car, do that rather than attempt to get your car through when it clearly won’t make it as you may be endangering your life and those of any passengers with you.

My first 4x4 was a Nissan Hardbody thereafter I started travelling all over the country. In 1992 we held a big 4x4 day with hundreds of Nissan families, and then the 4x4 bug really bit. A friend Monty Brett and I started running 4x4 courses at the Hennops Off-road Trail just outside of Johannesburg. At first we offered day-and-a-half courses that started on Friday afternoon and finished on Saturday afternoon. Hannes Grobler the Rally Ace regularly assisted, and we reached a nice balance between our two styles and our skills.
