    Food deliverymen (送餐员) are always in a hurry. They wear blue, red or yellow helmets (头盔) and many of them don’t follow traffic rules. They drive on the wrong side of the road and run red lights. They use mobile phones while driving.

In the first half of 2017, food deliverymen had 76 traffic accidents in Shanghai, according to Shanghai Public Security Bureau (上海公共安全局). That means every two and a half days, a food deliveryman will die or get hurt on the road.

What makes deliverymen put themselves into such a danger? The strict rules of the food delivery service companies and the worried customers (顾客) may be the answer. Many companies will fine (罚款) a deliveryman up to 2,000 yuan if he fails to deliver an order on time, reported China Daily. Fines also go to those who get bad reviews (评价) from customers.

To solve the problem, food delivery service companies need to do some changes. Some cities are also taking action. Shanghai has asked companies to train their deliverymen on traffic rules and safety. Now in Shenzhen, if a deliveryman breaks traffic rules more than twice, then he can’t do the job for a whole year.
