Idaho does not require an annual vehicle safety inspection. Does that make it acceptable to drive with unsafe brakes?
Correct answer: No; the driver is responsible for correcting unsafe equipment.
The absence of annual inspection does not permit operating a mechanically unsafe vehicle. Correct equipment defects before driving.

You have scraped a small opening in a snow-covered windshield. Is that enough to start driving?
Correct answer: No; clear snow, frost and other obstructions from the windows needed for full visibility.
