East Riding of Yorkshire Council has alerted drivers that they will be switching off street lights along two main roads as part of an energy-saving pilot.
The council was awarded £3.3m to study more environmentally friendly ways of lighting main roads, as more efficient car headlights could make some lampposts redundant.
The trial is part of a three-year, UK-wide £30m programme funded by the Department for Transport that aims to make the local highway network much greener.
East Riding of Yorkshire Council will run the pilot for 12 months and the behaviour of drivers, cyclists and pedestrians will be closely monitored using AI-powered thermal imaging cameras.
