Don't understand the question. There is no law saying there has to be bike lanes or bike paths.
Unless they're planned in from the beginning, they steal space from the other lanes, making them narrower. And it's also common that they'll start and stop in strange places, leving riders stranded in mid-traffic. A badly planned bike lane is often worse than no bike lane at all.
Yes, there is a pedestrian walkway on the Brooklyn Bridge that is divided into two lanes: one for foot traffic, and one for bicycles.
High Occupancy Vehicle (HOV) lanes.
No. Most bike paths do not allow motorized traffic. Read the specific bike paths rules. 49cc scooters are now classified as 'low power scooters'. This does not mean they are the same as a bicycle. 49cc scooters can ride in bike lanes though.
If the Engine is 50cc or larger it is Illegal to ride in a bike lane
One way to make transport easier and cheaper is to invest in public transportation infrastructure to provide more options for commuters. This could include expanding bus and train services, creating dedicated bike lanes, and implementing ridesharing programs. Additionally, offering incentives for carpooling or telecommuting can help reduce traffic congestion and overall transportation costs.
Legally, when riding a bike, you must ride in the same direction as traffic, the right lane in the US. You should ride as far to the right as is safe (unless you are turning left). It is illegal and unsafe to ride in the opposite lane (the left lane in the US).
No, but it is frowned upon. Some cities have bike lanes to stop people from riding on sidewalks.
Most cities have some bike lanes, somewhere.
Since the bike lane is assigned to the bicyclist, they always have the right of way in their lane. If you need to move to the right to make a right turn, you must yield to any bikes in the bike lane.
Use the Acro bike to get across when there is a gap in the lane do a sideways bike jump to get across.
