Tennessee Law Enforcement Training Academy (TLETA) Week 10 Practice Test

In driving terms, the apex of a turn is the innermost point of the curve—the spot closest to the inside edge of the road where you aim your line through the corner. This position lets you take the most efficient path, keeping steering input moderate and preserving speed as you transition from the turn to the straightaway. From the apex, you can begin to straighten the wheel and accelerate out, staying close to the inside until you’re past the turn. It’s not the entry, not the exit, and not just any mid-turn point—the apex is specifically the inner-most point that defines the best line through the corner. The idea of a “high point” isn’t the right way to describe it, since apex refers to position relative to the inside of the curve, not vertical height.
