The traffic police reminds you that the second half of the sentence

What you want to ask is that the traffic police reminds you what the second half of the sentence is. When you are on the road, safety is a blessing.

Usually, when the traffic police send text messages to drivers to remind them to travel safely, they will write, "Safety is a blessing for people on the road."

The main responsibilities of the traffic police are to maintain traffic order, handle traffic accidents, investigate and correct road traffic violations, and be responsible for the registration and management of motor vehicles.
