“Okay, so this is a road sign about going downhill. It’s a 10% slope, which is, in old money, it’s one in 10. It’s not a really, really steep hill, but you need to consider a lower gear because you want to get some engine braking to control your speed.
Don’t rely all the time on your brakes, but remember that the car behind will benefit if your brake lights are showing. So, use your engine braking, maybe change down a gear, and also put your brakes on to let the guy behind know that you’re controlling your speed.”
