~ Drive through the flood very slowly so not to cause a bow wave that could damp the electrics & stop the engine.
~ If water goes down the exhaust pipe into the engine you will cause terminal damage to your engine. If you decide to drive through use 1st gear, keep the engine revs up (gas) & slip the clutch to the bite to keep the speed down so that you do not cause the bow wave.
~ If you have oncoming traffic on a narrow road, let them through the flood first so that you are not affected by their bow wave.
~ Driving at speed through water can cause aqua-planning, this is where you are driving on top of the water! Your steering control will be lost & will feel incredibly light. Come off the accelerator & let your engine breaking slow you down. Do not break. As you slow down the car will come back down to the road
