Lack of grip to the road wheels

Avoid areas with oil and oil slicks
It is clear that such situations should be avoided whenever possible (trying to avoid a dangerous sections) or to use special techniques of driving.
Consider the types of hazardous sites.
Oily or covered with fresh cementitious materials (for example, has just laid asphalt) road - very slippery. Seek out any possibility of such a plot to overtake. In hot weather, oil stain on the road can be clearly seen, go around it. Do not drive in deep puddles
Puddle can be deep and 1 cm and 1 m. Just an idea of the depth is not possible, this should still drive into the water. But then ... may be too late. So try to drive around parts of the road, hidden by water. Under the water can hide various dangers. Moreover, after a journey of deep puddles can get wet brake pads and brakes failed, could stall the engine, etc.
Stay on track
If you can clearly discern the track laid by other vehicles driving on it. In a rut tire adhesion better.
On bands with more heavy traffic ice melts faster, so the movement of such bands is safer than where the car is small and, therefore, the ice crust on the road surface lasts longer. When the road is covered with melting ice, and avoid moving the strips with light traffic
It should also be wary of sites with no melted ice occurring in the shade of trees or buildings. Please note that the ice on such closed parts of the sun melts slower and closer to the evening quickly freezes again, even during the day slightly thawed.
Be especially careful when approaching bridges and overpasses. There's an icy crust on the road appears earlier than elsewhere, but disappears later. In these areas of high risk, avoid sudden movement of the steering wheel and pedals sharp taps of the "gas and brake.
Unnecessarily not overtake
Changing lanes on a slippery road - not the best idea of those that come to mind for drivers. Therefore it is better to stay in his lane. Even a simple lane change on slippery roads facing adversity, but overtaking is all the more. This maneuver is dangerous and in good road conditions and with poor adhesion is extremely risky.
Beware of snow, sand drifts and wet leaves
Go around sand and snow drifts, mud or fallen leaves. Wet leaves make the road surface is slippery as ice. If you say, try to slow down on the road, covered with wet leaves, it will almost certainly lose control of the car.
If you need to stop looking for a place on the road, free from the above hazards: ice, snow, leaves and sand. If such sites do not, for example, when driving in winter on the country road, preferably to stay on dry compacted snow. If there often stayed up to you, the snow may be "polished" to a state of the ice. Beware of this. And stop, and further and start from this place will be very difficult.
Do not stop the deterioration of the traffic conditions on the rise. Stay better before the upgrade or after it. Remember that starting on the rise in low grip - is difficult and dangerous.
If the ascent and descent is not the end, better to stop on the way down. Trogatsya will be easier.
