Sharing the Road & Hazards

The big idea

What this topic is really about

Avoid positioning your vehicle in a large transport truck's blind spots.. Large trucks have extensive blind spots, sometimes called no-zones, directly behind, immediately in front, and along both sides, with the right side being the worst.

Ease off the accelerator during hydroplaning.. Hydroplaning happens when a film of water lifts the tires off the road surface, so the safest reaction is to gently take your foot off the accelerator and avoid sudden steering or braking.

How it works

See the mechanism

When blinded by oncoming high beams, look toward the right edge of your lane and slow down to maintain control and safety.

Trucks have extensive blind spots, and lingering in these areas means the driver cannot see you. Trace the diagram above to fix how the pieces of Sharing the Road & Hazards fit together.

Worked example

An exam-style question, fully explained

When sharing the road with a large transport truck on the highway, where is the most dangerous place to position your vehicle for an extended time?

Identify what the question tests: When sharing the road with a large transport truck on the highway, where is the most dangerous place to position your vehicle for an extended time.
Large trucks have extensive blind spots, sometimes called no-zones, directly behind, immediately in front, and along both sides, with the right side being the worst.
Lingering in these areas means the driver cannot see you and may change lanes or stop without warning.
A useful guide is that if you cannot see the truck driver in their mirrors, they cannot see you.
Why it matters: Trucks have extensive blind spots, and lingering in these areas means the driver cannot see you. This can lead to unexpected lane changes or stops.

Answer:In the truck's large blind spots, especially directly behind and beside it

Common mistakes

Traps the examiner sets

Many drivers underestimate the size of a truck's blind spots or believe the driver can see in every direction.
Panic braking or sharp steering during hydroplaning can worsen the situation.
Some drivers may be unsure about the exact distance required or may not realize that this rule applies even when the cyclist is riding in a designated bike lane. Others may think that the distance can be adjusted based on the speed of the vehicle or the road conditions, but the law specifies a minimum of one metre where practicable.
Some drivers may be tempted to retaliate by turning on their own high beams, but this can actually make the situation worse. Others may stop in their lane, which is not a safe or legal option.
Hydroplaning happens when a film of water lifts the tires off the road surface, so the safest reaction is to gently take your foot off the accelerator and avoid sudden steering or braking.
