When no dedicated bike lane is provided, cyclists are governed by the same rules as motorcyclists. That means that they can (and should) take up the full lane just as a car would, but actually doing that tends to evoke negative responses from car drivers. In jurisdictions that allow it, lane splitting is both faster and less likely to trigger road rage, though probably more dangerous.
