Foreign born drivers are 18- 20% of all drivers, and closer to 50% in California, where the supply chain for imported goods is choked up. The Bureau of Labor Statistics asks if the truck driver labor market is broken. The Financial Times reported in September how the trucking industry is lobbying for higher temporary worker quotas for truck drivers. The UK, having driven out foreign drivers due to Brexit, is now issuing more visas, in part in response to panic over shortage of fuel at gas stations.
