You may park on the right-hand side of the road primarily when the street is a one-way street, where parking on either side is allowed because both sides are facing the same direction of traffic flow. This is important because vehicles have red reflectors on the back to enhance visibility to other drivers approaching from behind, and they lack these reflectors on the front, so parking facing oncoming traffic (i.e., on the right side of a two-way street) is generally not allowed as it reduces visibility and can confuse other drivers. Additionally, parking on the right side might be permitted in designated parking bays or spaces marked for such use. At night, if you park on the right-hand side (on a one-way street), you should ensure your vehicle orientation aligns with the direction of traffic flow, using appropriate lights for visibility. Parking on the right is generally prohibited on two-way streets except where specific local regulations or marked areas allow it.

In summary, parking on the right side of the road is mainly allowed:

• On one-way streets
• In marked parking bays or designated parking areas
• When your vehicle faces in the direction of traffic flow, especially at night for safety reasons

Outside of these conditions, parking on the right side of a road is commonly prohibited to avoid obstructing traffic and ensuring safety.
