Speed Limits
Ala. Code § 32-5A-171 — 30 in an urban district, 55 on most highways, 70 on an interstate
No one drives faster than is reasonable and prudent for the conditions and the hazards there are. A driver keeps to a safe and appropriate speed near and through an intersection or railroad crossing, around a curve, near a hill crest, on a narrow or winding road, and when pedestrians, traffic, weather or the road call for it.

| Where | Maximum unless posted otherwise |
|---|---|
| WhereAny urban district | Maximum unless posted otherwise30 miles per hour |
| WhereAn unpaved road | Maximum unless posted otherwise35 miles per hour |
| WhereA county paved road in an unincorporated area | Maximum unless posted otherwise45 miles per hour |
| WhereOther highways, with fewer than four lanes | Maximum unless posted otherwise55 miles per hour |
| WhereA highway with four or more lanes | Maximum unless posted otherwise65 miles per hour |
| WhereAn interstate | Maximum unless posted otherwise70 miles per hour |
These are the maximum lawful speeds except where a special hazard requires a lower speed to stay reasonable and prudent.
Too slow, too. No one drives so slowly as to impede the normal and reasonable movement of traffic, except when a reduced speed is needed for safety or by law, and posted minimum speeds apply where set.
