Learn what matters. Practice with purpose. Walk into the DOT prepared.

Topic 01

Right-of-Way & Intersections

Exam Difficulty:Medium

Understanding who has the right-of-way is one of the most heavily tested areas on the Iowa DMV exam. Most failures occur here.

Must-Know IA Tip: Mountain Road Yield Rule

When two vehicles meet on a steep single-lane mountain road where they cannot pass, the vehicle facing downhill must yield by backing up until the vehicle going uphill can pass safely.

Core Rules & Tested Concepts

  • At intersections without signs, yield to the vehicle on your right if it arrives at the same time.
  • At T-intersections, vehicles on the terminating road must yield to vehicles on the through road.
  • When making a left turn, you must yield to oncoming vehicles close enough to be a hazard.
