[[Warning sign]]s (alerting drivers of unexpected or hazardous conditions) tend to be more verbose than their Vienna Convention counterparts.<ref name="Johnson" /> On the other hand, MUTCD guide signs (directing or informing road users of their ___location or of destinations) tend to be less verbose, since they are optimized for reading at high speeds on freeways and expressways.<ref name="Johnson" />

The MUTCD lacks a [[Mandatory sign|mandatory sign group]] like the Vienna Convention does, a separate category for those signs like "Right Turn Only" and "Keep Right" that tell traffic what it must do instead of what it must not do. Instead, the MUTCD primarily classifies them with the other [[regulatory sign]]s that inform drivers of traffic regulations.<ref>{{citationCite journal |last=Babić |first=Darko |last2=Babić |first2=Dario |last3=Fiolic |first3=Mario |last4=Ferko |first4=Marija needed|date=May2022-10-12 2021|title=Road Markings and Signs in Road Safety |url=https://www.mdpi.com/2673-8392/2/4/119 |journal=Encyclopedia |language=en |volume=2 |issue=4 |pages=1738–1752 |doi=10.3390/encyclopedia2040119 |issn=2673-8392}}</ref>
