===Comparison to trams===
''Note: As there are numerous variations of tram and [[Light rail|light-rail]] technology, the disadvantages listed may be applicable only with a specific technology or design.''

*Like any bus, much less capacity than trams.
*More control required{{snd}}Trolleybuses must be driven like motorbuses, requiring directional control by the driver.
*Higher rolling resistance{{snd}}Rubber-tired vehicles generally have more [[rolling resistance]] than steel wheels, which decreases energy efficiency.
*Less efficient use of right-of-way{{snd}}Lanes must be wider for unguided buses than for streetcars, since unguided buses can drift side-to-side. The use of guidance rail allows trams running in parallel lanes to pass closer together than drivers could safely steer.
*Difficulties with platform loading{{snd}}Implementation of level platform loading with [[platform gap|minimal gap]], either at design stage or afterwards, is easier and cheaper to implement with rail vehicles.
*Wear of rubber tires leads to significant [[rubber pollution]].
