There are a plethora of secrets and unlockables for players to uncover as they journey through the Free Roam game mode in Mario Kart World. This mode presents every track in the game connected by expanses of roadways and other locations. Some of these unlockables will give players access to new game modes once they have been found, while others give out some less-than-exciting rewards, to be perfectly honest.

One of the unlockables that fall into the latter category is the Question Mark Panels, which will give players more stickers to unlock. While it doesn't do much to change any of the gameplay for players, finding every Question Mark Panel is going to be paramount for anyone looking to get that 100% in the game. So, for any dedicated drivers looking to find everything that Mario Kart World has to offer, this guide is here to help them find every Question Mark Panel on the Whistlestop Summit racetrack.

All Yellow Question Mark Panels in Whistlestop Summit

Question Mark Panel 1 Location (Whistlestop Summit)

The first panel for players to find can be done by going to the game's starting line by fast traveling to the track from the game's map. Here, they need to turn around immediately, and they can spot a small passage through some buildings along the edge of the track's final curve.

If players drive through this passage and take a left, they will find the first Question Mark Panel hanging out past the Yoshi food stand.

Question Mark Panel 2 Location (Whistlestop Summit)

The second Panel can be found by turning back around and heading back toward the starting line. As they approach it, players can turn slightly to the right and find a group of red roofs that they can drive off the track to access.

Driving on the rooftops will reveal the second Question Mark Panel on one of the opposite slopes of the roof. Driving over it will net the player the second Question Mark Panel on the course.

Question Mark Panel 3 Location (Whistlestop Summit)

The next Panel is also right around the starting line area. Players need to get back to the racetrack, and when facing the starting line again, look to the left instead. Here, they can go through a small hallway in the building and then turn left on the other side to see some stairs.

If players drive up these stairs and then turn around, they will find the next Panel on the building roof.

Question Mark Panel 4 Location (Whistlestop Summit)

The fourth Panel can be found by driving along the track until the player crosses the railway bridge and into the large curve that leads upward. Here, players need to brake and turn around to look at the center of the curve. They will find a small, stone pathway that they can drive up.

Driving up this slope will bring them to a large road, where they need to go right and continue along until they see a Yoshi Food Stand. Just beyond this, the player will find the panel for them to drive over.

Question Mark Panel 5 Location (Whistlestop Summit)

The final Question Mark Panel is found by driving up the stone pathway from the previous panel as well. However, when the player gets to the wide road, they need to turn left and head down the slope until they reach a tunnel on their right.

Taking a right and driving through that tunnel is going to take the player to the final Whistlestop Summit Question Mark Panel, right before a glide boost.
