Assuming the roads are safe and clear, how fast can you legally go? Well, it depends on where you are. In a posted school zone, the speed limit is usually lower than the surrounding area. In residential districts, the speed limit is either 25 or 35mph. Specific sections of rural and interstate highway have a speed limit of 70mph, but some sections may be 65, 60, or even 55mph, so watch out for posted changes.

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 into the Tennessee River.
