My friend's a cop and he got me some of those road strips with spikes and caltrops police use to blow out the tires of fugitives, and I want to lay them down at various points on the road as a joke. Where in the road do you suggest I lay them down?

Wherever it’s not safe for vehicles to drive.  For example, on a speed bump, the broken parts could fall off and cause damage. A busy street that’s frequently used for turning, that would also be dangerous.
