Alabama’s Basic Speed Law Comparing statutory, posted, and advisory speed limits. Alabama basic speed law provides that you must never drive a vehicle at a speed that is faster than reasonable under existing conditions.

Speed may not always, in itself, be the primary cause of traffic crashes. Speed all too often is the factor that turns a minor mishap into a fatal accident The greatest danger of excessive speed lies in the increased severity rather than the frequency of collisions.

The basic speed law is set for speed limits for normal driving conditions.

Things To Consider When Deciding On Your Speed Road Conditions: > Paved, Gravel, Dirt, etc. > Ice, Snow, Rain, etc. Vehicle Conditions: > Tires > Old versus New > Size Your Condition: > Fatigue, Anger, etc. > Eye Sight

What might be a reasonable speed at one time may not be reasonable at another time because of conditions.
