When to turn off your cellphone: What you should know

When you’re trying to save money, it’s worth noting that it’s often wise to check to see if you’re on a toll road, and not just to turn on the GPS.

There’s no good reason to rely on the speedometer on a car traveling at highway speed, since it will only show you the fastest road.

In some cases, like when you’re driving in a heavy snowstorm, it might be best to just turn off the GPS if you’ve had a rough night ahead.

It’s not an excuse to not use your phone, but you can make the best use of the time you have available.
