Be cautious of oil patches. Do not slam on the brakes; instead, steer through. Patches will be small in most cases.
Before taking a bend, especially a sharp bend, always shift into a lower gear. As you approach the bend, your speed should be at its slowest, and both hands should be on the steering wheel. When driving around a bend, this slow in/fast out technique gives you the most control.
Double your normal following distance from 3 seconds to 6 seconds to increase your space cushion.
Switch on your headlights.
Other vehicles in the rear and in blind spots should be avoided because they are difficult to see through rain-splattered windows.
