What is a truck's no-zone?

The four blind-spot areas around a large truck — front, rear, and both sides — where the truck driver cannot see your vehicle. If you can't see the driver's face in their side mirror, you're in one.

How much room do you give a cyclist when passing?

At least three feet of clearance in most states — and more at higher speeds. Slow down and wait for a safe gap rather than squeezing past in the same lane.

When can you pass a stopped school bus?

Only when you're traveling the opposite direction on a divided highway — in states that allow it at all. On any undivided road, traffic in both directions must stop for flashing red lights and remain stopped until they're off.

Sharing the Road: Trucks, Motorcycles, Bicycles, and School Buses

Sharing-the-road questions have one theme: the other road user has a limitation you can't see from your seat. Trucks can't see you, motorcycles can't be seen, cyclists can't survive contact, and school buses unload children who don't check traffic. Learn each limitation and the rules explain themselves.

Trucks: the no-zone

A loaded semi has blind spots — no-zones — on all four sides: directly in front, directly behind, and along both sides, with the right side largest. The working rule: if you can't see the driver's face in their mirror, they cannot see you. Pass on the left, pass without lingering, and never cut back in until the whole cab shows in your rearview mirror. Trucks also need far more stopping distance and swing wide on right turns — never slide into the gap beside a turning truck.

Motorcycles

Motorcycles are the road's disappearing act: narrow enough to hide in a mirror's blind spot and small enough that drivers misjudge their speed and distance. The deadliest scenario is a car turning left across an oncoming motorcycle — look twice specifically for bikes before any left turn. Give riders a full lane (lane sharing is their choice, never yours) and a four-second following distance; a pothole that a car ignores can put a rider on the ground.

Bicycles

Cyclists are vehicles with full road rights and zero armor. Most states codify a three-foot minimum passing clearance — slow down and wait for room rather than squeezing past. After parallel parking, check for riders before opening your door; a door opened into a bike lane is a serious, and in many states citable, crash. At intersections, yield to a cyclist going straight before you turn right across their line — the classic 'right hook.'

School buses: the strictest stop in traffic law

Flashing yellow lights on a bus mean it's about to stop — slow down and prepare. Flashing red lights and an extended stop arm mean stop, in both directions on any undivided road, at least 20 feet away in most states, and stay stopped until the lights stop and the arm folds. The only common exception is oncoming traffic on a divided highway — and the definition of 'divided' varies by state, with a few (like New York) requiring even that traffic to stop. Passing a stopped school bus carries some of the harshest penalties in the vehicle code everywhere.
