Overtaking a truck on the highway requires extra caution due to the truck’s size, longer stopping distance, and significant blind spots. The core aim is to complete the pass with ample space and ensure the truck driver can see you at all times. Here are key things to be mindful of:

• Check blind spots and the truck driver's line of sight
  • Trucks have large blind spots on the sides, behind, and in front. If you can’t see the driver in the truck’s side mirrors, assume you’re not visible to them. Stay out of those zones while you plan the pass.

• Maintain a safe following distance and prepare to accelerate
  • Leave extra space behind the truck before you begin to overtake so you have enough time to complete the pass without forcing the truck to brake abruptly. Do not cut back in too early; return to your lane only when you can see the truck's headlights in your rear-view mirror.

• Look for a clear, straight section with good visibility
  • Only overtake when you have a long, straight stretch with no bends or dips that could obscure oncoming traffic. If there’s oncoming traffic, do not attempt the pass. If there’s no overtaking lane, wait for a safe opportunity.

• Ensure there is enough space and it’s legal
  • Confirm there is no oncoming vehicle in the opposite lane, you have a safe clearance to pass, and that legal criteria are met for overtaking a heavy vehicle. Do not overtake near curves, hills, intersections, or when visibility is compromised.

• Be mindful of speed and momentum
  • Increase speed only to pass and never slow down in front of the truck after you’ve completed the pass, as this can surprise the truck driver. Maintain a steady, safe speed as you move back into your lane.

• Be patient and avoid pressure from other drivers
  • Don’t be pressured by following vehicles; if safe space isn’t available, wait for a better opportunity.

• After overtaking, recheck the truck’s position
  • Re-enter your lane only when you can clearly see the truck ahead in your mirrors and you’ve created a safe gap.

Practical steps to follow:

• Signal early to indicate your intent to overtake.
• Check for clear road ahead and no oncoming traffic in the opposite lane.
• Move into the left lane when safe, build enough speed, and pass quickly but smoothly.
• Return to your lane with a clear margin, ensuring you see the truck in your rear-view mirror before merging.
