I got in my lexus driving down the road my check engine light started flashing and my track off light is solid what could it be

Do not drive your Toyota with the CEL flashing/blinking. A blinking CEL indicates that your vehicle's engine is misfiring, which could severely damage your catalytic converters. A misfire is when one or more of your engine's cylinders are not providing power to the vehicle, with raw fuel possibly running into the catalytic converter.

Hello, a flashing check engine light is typically a sign of an engine misfire. This can cause further damaged to powertrain and exhaust components, so have this checked without delay.

When a Toyota produced vehicle has a check engine light, typically it will disable the traction control so both lights are probably related to one cause. Have it checked soon, the misfire can create other issues.
