AAA Driver's Ed Permit Practice Test

When you’re towing a trailer, you need more following distance than you would with just a car because the added length and weight increase both the stopping distance and the potential for trailer sway. Even with good traction and clear visibility, that extra mass behind you means you’ll need more time to react and brake without getting too close to the vehicle in front. The extra space reduces the risk of a rear-end collision if the lead vehicle slows suddenly and gives the tow vehicle and trailer time to stop and settle through turns or braking. Among the options, choosing a moderate increase in following distance aligns with the safety guidance for towing: it’s enough to account for the trailer’s influence without unnecessarily hampering traffic flow. In poorer conditions, you’d increase the margin even more.
