At least 21 people were injured following a four-car collision in Yuen Long on Friday.
Police received reports at about 6.30pm, saying two buses, one light truck and a private vehicle crashed on Yuen Long Highway.
Nine men and 12 women suffered light injuries. None of them were trapped.
The Transport Department said it closed some Tuen Mun-bound lanes on the highway for the recovery operation.
It also called on motorists to use other routes because traffic is heavy in the area, as the slip road at Shap Pat Heung Interchange was also closed.
In a statement, bus operator Kowloon Motor Bus (KMB) said two of its buses, 276B and 269B, were involved in the accident when passing through Pok Oi Interchange.
It said 20 passengers and a driver were injured.
KMB added that staff will visit injured passengers, and investigate the cause of the accident.
