5. Watch Out for Trucks
Trucks generally travel slower than passenger cars, but it's wise to keep an eye on them. If truck drivers suddenly reduce speed to match the limit, it often signals an upcoming speed camera. Truckers frequently share this information among themselves, so they know about it before you'd hear it on the radio. Therefore, if you notice trucks around you slowing down, make sure you're also adhering to the speed limit. Of course, it's always best to follow the speed limit regardless.
