If you lack one sense, then you should use your other sense more.
In this case, you lack hearing... so you should look around more.
Using "I'm deaf" as an excuse can be pointless when your eyes could have done the work just as well.
When you're crossing the street, you need to look both ways before crossing the street. If you're crossing a 2-way street (in America), then you would focus more on your left until you get halfway... then focus more on your right as you finish the crossing.
When you're driving, don't keep your eyes forward 100% of the time. Look around, be alert. I know people who keep their eyes on the road so much that they don't even notice ANYTHING that's happening around them. They don't even know there's a firetruck or an ambulance behind them. :roll: Check your mirrors from time to time. Watch the cars around you. (If you see them trying to move out of the way, it's likely cuz an emergency vehicle or a police car is coming through. That's one sign to look behind you and around you.)
