To avoid upsetting your vehicle's balances accelerate into the turn use the brakes don't make sudden movements don't let people sit in the back

## Step 1<br />The problem is about driving safety and the best practices to maintain balance while driving. The options provided are:<br />- Accelerate into the turn<br />- Use the brakes<br />- Don't make sudden movements<br />- Don't let people sit in the back<br /><br />## Step 2<br />Analyzing each option, we can see that:<br />- Accelerating into the turn can destabilize the vehicle and is not a safe practice.<br />- Using the brakes can also destabilize the vehicle, especially if done suddenly.<br />- Not letting people sit in the back is not directly related to maintaining balance in the vehicle.<br /><br />## Step 3<br />The only option that directly addresses the issue of maintaining balance is "Don't make sudden movements". Sudden movements can destabilize the vehicle and upset its balance.
