Qualifying traffic in English

I am interested in qualifiers for traffic ordered by fluidity. Here is what I would personally use:

  • Fluid Traffic
  • Heavy traffic
  • Congested

However, the last one would qualify the transportation layer rather than the traffic itself. Are there other qualifiers that can be used for the latter, respectively more qualifiers that simply escape the non-native speaker?


  • "traffic" (noun)
  • Vehicles moving on a road or public highway. Google
  • All the vehicles driving along a certain road or in a certain area MW
  • no traffic
  • very light traffic
  • light traffic
  • moderate traffic
  • heavy traffic
  • slow traffic
  • congested traffic
  • traffic jam

One common idiom for traffic congestion is bumper-to-bumper traffic, which suggests traffic is so dense that cars' bumpers are practically touching.
