Lawmakers on Saturday urged the government to focus on the finer details of an incoming scheme that will allow cars from Guangdong to drive into Hong Kong.

From as early as November, motorists across the border can apply for the Southbound Travel for Guangdong Vehicles scheme. Drivers can park their vehicles at the airport with 100 cars per day allowed access to urban areas in the initial phase.

Transport sector lawmaker Frankie Yick says he believes the city can handle more vehicles heading south but that he thinks the administration still has work to do.

"There are quite a number of details that need to be clarified. Let's say, how drivers are going to settle the toll fees," Yick said after a radio programme.

"And also, a lot of people are concerned about the driving behaviour... The government should do something to alert or educate those potential drivers coming down to Hong Kong."

Roundtable lawmaker Michael Tien also said that there might be differences in driving cultures.

"There are many subtle nuances that are different. But as time progresses, the gap will narrow," Tien said.

Secretary for Transport and Logistics Mable Chan has said the scheme's implementation is one of her bureau's main tasks this year.

"We will closely monitor the scheme's implementation and consider further opening up more places based on the experiences and feedback from all parties," she wrote on her official blog.
