Who's liable when there's a crash involving a motorist who has received a "wave-through" at an intersection or on a busy street?

• The waver. With the great power to surrender the right-of-way comes great responsibility.

• The wavee. No one is forcing you to accept the wave-through. If you do, it's up to you to make sure the coast is clear before going.

• The driver who crashed into the person being waved through.
