Assuming the roads are safe and clear, how fast can you legally go? Well, it depends on where you are. Residential districts might have a speed limit of between 20 and 40mph. In a posted school zone, the speed limit is normally lower than the surrounding areas. Specific sections of highway might have a speed limit of 65mph, but most other areas, including highways not otherwise posted, usually have a speed limit of 45 or 55mph.

Other than that, you are likely to see speed limit signs indicating a wide range of limits based on a variety of conditions, such as constructions zones, school zones, or half-finished-then-abandoned bridge zones. Just remember to always drive no faster than the speed limit (and slower still if conditions are poor) so that you don’t go ramming into the rear end of a hatchback or flying off the side of a bridge.
