To establish proper visual lead time on a city street, you should be looking at least 15 seconds ahead, which will work out to be at least a block ahead (about 600 feet). On the highway, you should also be looking at least fifteen seconds ahead as well, which works out to be at least one-quarter of a mile ahead.
In California, a car can enter the bike lane only within 200 feet of the upcoming intersection. Of course, any bikes in the lane still have the right of way, and drivers have to yeild to the bikes. You should look over your shoulder just in case there is someone in your blind spot, and then move into the bike lane. You can stay in the bike lane for only 200 feet when you are making a right turn. Hope that helps. Lifes.Funny. It is not permissible to drive in a bike lane. If you are turning right and there is a bike lane, you need to look over your right shoulder, check your mirrors and make the turn from the vehicle lane. The bike lane is usually much narrower than a traffic lane anyway.
