What should you do if you want to overtake a tractor but aren’t sure that it’s safe?

Explanation: Following a tractor can be frustrating, but never overtake if you're unsure whether it's safe. Ask yourself: 'Can I see far enough down the road to ensure that I can complete the manoeuvre safely?' It's better to be delayed for a minute or two than to take a chance that may cause a collision.
