A delivery note gives a postcode that leads to the rear of a shopping centre, but the lorry entrance is signed on another road. What should the driver do?

1. Stop safely and verify the correct HGV access route before committing to the turn
2. Reverse from the public road if the first entrance is wrong
3. Enter the pedestrian service yard because it is closer to the postcode
4. Ignore local signs if the delivery note has the right customer name
