California Driver Handbook - Special Driving Situations
The driver’s blind spots are shown here. If you look only in your mirrors, you cannot see vehicles in these blind spots. Turn your head to see if a vehicle is in one of these blind spots. Do not linger in another driver’s blind spot. As soon as you can, drop back or pass the vehicle.
The faster your speed, the less control you have of your vehicle. Rather than driving at the legal posted speed limit, adjust your driving speed for road conditions or whatever affects the safe operation of your vehicle
On curves, there is a strong outward pull on your vehicle, which is especially dangerous when the road is slippery. Rain, mud, snow, ice, and gravel make the road slippery. If a speed limit is not posted before a curve, you must judge how sharp the curve is and adjust your speed accordingly. Slow down before you enter the curve; you do not know what may be ahead (stalled vehicle, collision, etc.). Braking on a curve may cause you to skid.
Collisions are more likely to happen when one driver goes faster or slower than the other vehicles on the road. If you drive faster than other traffic, you increase your chances of being involved in a collision. Speeding does not save much time. Driving slower than other vehicles or stopping suddenly can be just as dangerous as speeding, if not more dangerous, because you may cause a rear-end collision or cause other drivers to swerve to avoid hitting your vehicle. If you are in the fast lane and you notice vehicles moving to the right lane to pass you, or a line of vehicles is forming behind you, the best thing to do is move into the right lane, when it is safe, and let the vehicle(s) pass.
