When driving near construction, you must be alert to the various ways traffic is being controlled and guided through the work zone. The best choice is all of the above because construction sites use flaggers who direct or stop traffic, signs or other devices that warn of changes and guide you through the area, and lane closures that reduce or shift your path and require you to merge or slow down. Flaggers may signal you to stop or proceed at specific speeds, so you need to follow their instructions exactly. Signs and devices inform you about reduced speeds, narrowed lanes, and the presence of workers or equipment, helping you anticipate what’s ahead. Lane closures change how traffic moves, so recognizing and adjusting early prevents abrupt braking or lane changes. In practice, slow down before entering the zone, increase your following distance, and be prepared for sudden stops or shifts in traffic. Stay attentive to workers and equipment, and follow all posted signs and directions.

Using a cell phone while driving creates a distraction that pulls your attention away from the road. Driving needs constant awareness of hazards, traffic, signs, and pedestrians, and quick, appropriate reactions. A phone conversation or text absorbs part of your mental resources, so you notice fewer details and react more slowly to dangers. Even hands-free calls still divide your attention, since the cognitive load of talking competes with driving tasks. So the general effect is reduced awareness and slower reaction time, which is why this option best fits.

A safe following distance is the cushion you need to react and stop if the vehicle ahead slows or stops suddenly. On normal roads, you should keep enough space to comfortably brake without hitting the car in front, which gives you time to perceive a hazard, decide, and act. That’s why this option is best: it focuses on leaving room to react rather than chasing the car ahead or crowding them. Tailgating leaves you with zero margin if that car brakes hard, following at the same distance doesn’t create any safety buffer, and staying inches behind is an unsafe habit that can’t cover you if conditions change. A practical guideline is the three-second rule (or more in poor weather or low visibility): pick a fixed point ahead, and ensure you pass it three seconds after the vehicle in front does. Increase that time in rain, snow, or icy conditions, or when following trucks or in heavy traffic.

Riding with the flow of traffic is the safest and usually required direction for cyclists on roads. When you travel in the same direction as other vehicles, you’re predictable to drivers, can use the same traffic signals, and are operating under the same expectations as other road users. This reduces the chance of collisions that can happen when you face oncoming traffic, where drivers might not anticipate a cyclist approaching from the front. Riding perpendicular to traffic isn’t a practical or safe way to move through roadways, and saying it doesn’t matter ignores a real safety and legal difference. If possible, stay as far right as practicable and follow local rules, adjusting only when you need to pass or avoid hazards.
