Smaller commercial vehicles usually don’t have governors to regulate engine rpm and the amount of fuel burned. To upshift a gasoline-powered vehicle that is not equipped with a governor, perform the following steps: 1. Start in low gear. Use only enough throttle to start the vehicle moving. 2. When the engine begins to accelerate, quickly shift into the next gear. Shift into higher gears as soon as you have the power. 3. As your vehicle’s speed increases and you begin shifting into the higher gears, allow the engine to develop more power before each shift so the rate of acceleration increases. 4. As you complete each shift, engage the clutch smoothly, and engage the throttle at the same time.
