Why is my Vauxhall Insignia shaking while driving?

I recently bought a used Vauxhall Insignia and I've noticed that it shakes while driving at high speeds. What could be causing this issue?

The first thing you should check is the wheel balance and alignment. If these are not properly adjusted, it can cause the car to shake while driving. I recommend taking it to a mechanic to have it checked.

Another possible cause could be worn out or unbalanced tires. Make sure to check the tread depth and condition of your tires. If they are worn out, it's best to replace them with new ones.

In some cases, the shaking could be due to a faulty suspension system. Check your shocks and struts for any signs of wear or damage. If needed, get them replaced to improve the ride quality of your car.
