City Traffic Laws

[Nathan Ross]

This researcher considers the legislation to amount to a pedestrian zone

Although the passage he puts in quotes ("although wheeled traffic was forbidden in the streets during daylight hours") does not appear in Caligula 44, but is a modern gloss; Suetonius only says that the messengers were ordered to drive straight to the Forum and deliver their messages to the consuls in person.

Since Caesar's law only seems to have applied to heavy goods wagons, and the law against other vehicles apparently dates to Claudius, there does not seem to have been a strict ruling banning lighter vehicles or horse riders under Caligula.
