- B Yes, as long as no cars are in sight
- C No, approaching drivers must be able to see you within 500 feet
- D No, approaching drivers must be able to see you within 1,000 feet
Show answer
C. No, approaching drivers must be able to see you within 500 feet
U-turns are not allowed on curves or near the crest of a hill where approaching drivers cannot see you from within 500 feet in either direction. They are also illegal in no-passing zones and where U-turns are posted as prohibited.
