What must you be aware of when driving your lorry through narrow passageways?

When driving a lorry through narrow passageways, it is important to remember that the exterior rear-view mirrors often extend beyond the vehicle's documented width. This means you need to be careful to avoid hitting obstacles with the mirrors. Additionally, the vehicle body can sway or tilt on uneven surfaces, which may cause parts of the vehicle to come closer to obstacles than expected. Both factors require extra caution to prevent collisions. The vehicle width stated in the documents does not include the mirrors, so you must mentally add their width when assessing if the passage is wide enough.
