However, there are many synonyms for tailbacks that can be used to describe this situation. Some alternatives include congestion, gridlock, snarl-ups, jam, bottleneck, and logjam. Each of these words effectively communicates the idea of slow-moving or stopped traffic caused by a buildup of vehicles. While they may have slightly different connotations or usages, they all convey the same general sense of frustration and delay that comes with being stuck in a tailback. Choosing the right synonym can help to add variety and interest to your writing or conversation about traffic.
