📖 Topic overview
This chapter covers how to choose a safe speed for the conditions you're driving in, not just the number on the sign. You'll learn why keeping a safe following distance behind the car ahead is essential, and how good driving means adjusting your speed and distance to match traffic, weather, and your own alertness.
The most tested ideas are recognizing when to slow down and increase your following distance — wet roads, heavy traffic, and reduced visibility all call for extra space and caution. You'll also want to understand why higher speed narrows your field of vision, and the "slow down or move over" rule for passing a stopped emergency, tow, or highway maintenance vehicle with its lights activated.
A common mistake is treating the posted speed limit as a target rather than a maximum — the safe speed for the conditions can be well below it. Another is forgetting that street racing and speed contests are illegal on public roads, no matter how quiet or empty a road may seem.
Why does driving faster reduce my field of vision?
As speed increases, your eyes must focus farther ahead to react in time, which narrows how much you can clearly see to the sides — at higher speeds your usable field of vision shrinks noticeably compared to standing still.
What should I do when I approach a stopped emergency or maintenance vehicle with its lights flashing?
The handbook calls this the "Slow Down or Move Over" rule — reduce your speed well below the limit, and if the road has multiple lanes going your direction, move out of the lane closest to the stopped vehicle.
Are speed limits always just a maximum I shouldn't exceed?
Not only — some roads also post a minimum speed limit, and drivers are expected to keep pace with the normal flow of traffic rather than driving unreasonably slowly, while never exceeding the posted maximum.
