China is expected to waive tolls for vehicles on four important national holidays, as part of an attempt to ease congested traffic during annual travel peaks.

The State Council approved the plan on Wednesday, and the Ministry of Transport, which initiated the idea, is now busy trying to figure out how to implement the waiver, according to an industry insider who did not want to be identified before an official announcement.

Passenger vehicles with seven seats or less will be exempt from tolls during Spring Festival, Qingming Festival (Tomb Sweeping Day), Labor Day on May 1 and National Day on Oct 1, China Land and Resources News, a newspaper under the Ministry of Land and Resources, reported on Tuesday.
