交警助手 is a free iPhone application developed by Long Luo. It falls under the category of Education & Reference and offers a range of useful features for traffic police officers.

The app provides a convenient way to search for traffic violation codes. Instead of flipping through a thick book, officers can now easily search for codes using keywords or precise code search. This saves time and ensures accurate enforcement on the road.

Another notable feature is the extensive database of vehicle announcements. With over 600,000 records and nearly 70GB of image data, officers can access crucial information related to vehicles.

交警助手 also includes a collection of commonly used laws and regulations. Users can view the full text of these laws and regulations and perform keyword searches across all documents. If a specific law or regulation is missing, users can request its addition.

Additionally, the app offers a feature to check license plate ownership and provides an overview of national highways. This information is valuable for traffic officers who need to identify license plate prefixes and have a general understanding of the national highway system.

Developed by experienced traffic police officers, 交警助手 is designed to be practical and user-friendly.
