The sign "Parking on sidewalks at an angle to the right at the beginning of the driving lane" indicates that drivers are allowed to park their vehicles at an angle to the right on the sidewalk. This means that when you see this sign, you can park your car partially on the sidewalk as long as it starts at the beginning of the driving lane.

However, it's important to ensure that you are not obstructing pedestrian pathways or causing any hazards for other road users. Always check local regulations and ensure that your parking complies with the rules specific to the area you are in.
