Among the countries listed below, Liberia, Nigeria, and the Philippines have ratified the Vienna Convention on Road Signs and Signals, while the United Kingdom has signed the convention but not yet ratified it.

[1] Botswana, Eswatini, Lesotho, Malawi, South Africa, Tanzania, Zambia, and Zimbabwe are all Southern African Development Community (SADC) members who drive on the left and use the SADC Road Traffic Signs Manual.

The Manual on Uniform Traffic Control Devices (MUTCD) used in the United States has also influenced signing practices in other countries.

Mandatory signs indicating an obligation to turn left do exist, but are not included in the list below since they are functionally mirror versions of signs indicating an obligation to turn right.
