Hi Caitlin,

Normal bus lanes are marked by a single yellow line reserved solely for approved vehicles during peak hours with periods in between for normal motorists use. The operating hours will be from Monday to Friday at 7.30am - 9.30am & 5pm - 8pm.

Full-day bus lanes are marked with a yellow and red line with the same purpose. However, it operates throughout the morning peak hour to evening peak hour from Monday to Saturday at 7.30am - 11pm.
