Mexico's transport and communications ministry (SCT) has published a bill to regulate heavy goods vehicles.
The regulations will specify the weight, dimensions and mandatory safety requirements for cargo vehicles travelling on state highways and bridges.
Under the proposed law, transporters will be held responsible for any damage incurred to federal infrastructure, SCT said in a release.
The regulations also set time limits for when cargo vehicles may circulate on public highways, to limit traffic congestion. Heavy goods vehicles will be allowed to transit from 06.00-18.30 and 00.00 to 06.00 Monday to Friday, and 06.00-14.00 on Saturdays.
The bill was drawn up by SCT with support from the finance ministry, state power company CFE, national cargo transport chamber Canacar and the national transport institute (IMT), among others.
The public has 60 days to submit comments concerning the bill, SCT said.
