The correct answer is: 1. From 5 AM to 10 PM.
New Zealand road rules establish specific driving time restrictions for drivers with a restricted license to enhance road safety. This type of license is typically obtained by novice drivers after acquiring a learner's license and passing certain tests, indicating that the driver has basic driving skills and knowledge but still needs to gain experience in practice to improve their safe driving abilities.
The purpose of this regulation for restricted licenses is primarily due to the fact that road conditions can be more complex at night (especially during late-night to early morning hours), such as limited visibility and more unpredictable traffic behaviors, which pose higher risks for inexperienced drivers. By restricting solo driving during these times, the likelihood of traffic accidents can be effectively reduced, providing a safer driving environment for novice drivers and allowing them to gain more experience and skills before facing higher-risk driving situations.
