Sharing the Road & Adverse Conditions
⏱ ~3-min readAceMark GuideWhat this topic is really about
Large trucks have extensive blind spots, called No-Zones, directly in front, immediately behind, and along both sides, with the right side being the largest. A good rule is that if you cannot see the truck driver's face in their mirror, they cannot see you. Avoid lingering beside trucks and pass on the left as quickly and safely as possible.
When hydroplaning, ease off the accelerator and keep the steering wheel steady until traction returns.. When hydroplaning, your tires lose contact with the road, so braking or steering hard can cause a skid.

This ensures the safety of the bicyclist, who has the same rights and duties as other drivers. A diagram for this topic isn't available yet — the worked example below walks the same reasoning step by step.
An exam-style question, fully explained
How far must a motorist in Illinois leave when passing a bicyclist on the road?
- Identify what the question tests: How far must a motorist in Illinois leave when passing a bicyclist on the road.
- Illinois law requires drivers to leave a minimum of 3 feet of space when overtaking a bicycle.
- If 3 feet is not available, you must wait until it is safe to pass.
- Cyclists have the same rights and duties as other drivers and may use a full lane when needed.
- Why it matters: This ensures the safety of the bicyclist, who has the same rights and duties as other drivers. Leaving 3 feet of space also accounts for potential swerving or unexpected movements by the bicyclist.
Traps the examiner sets
- Some drivers may think they need to leave more space than 3 feet, or that they have no specific distance requirement when passing a bicyclist. However, leaving insufficient space can lead to accidents or injuries.
- Learners often confuse the Dutch Reach with preventing rear‑end collisions or hydroplaning, rather than its specific purpose of avoiding dooring incidents.
- Drivers often think they should brake or steer sharply to correct hydroplaning, but this can worsen the skid.
- Avoid lingering beside trucks and pass on the left as quickly and safely as possible.
